You can route your measurements directly to the internal DMM, or you can connect to external instruments through the analog bus connector on the rear of the mainframe. And since you have four 2-wire buses, you can dedicate one bus for use with the internal DMM and use the other three buses for module extensions or additional signal routing between modules, reducing your wiring needs. You can deine up to 500 switch sequences to control complex signal routing and the order of switch closures. Assign a sequence, give it a name and then execute it with the name you created. Switch sequences are downloaded and stored in the instrument for ease of programming and increased throughput. External trigger capabilities make it easy for you to time and synchronize measurements and other events. This can help you determine when to begin or end an acquisition. 04 | Keysight | 34980A Multifunction Switch/Measure Unit - Data Sheet Measurements you can trust Get proven performance from Keysight instruments, with the resolution, repeatability, speed, and accuracy you've come to expect. The 34980A offers built-in signal conditioning and modular lexibility. When you use it with the internal DMM, you can conigure each channel independently for the measurements you choose. It includes a variety of features that give you conidence in your measurements: - 61/2 digits of resolution with .004% of accuracy with DC voltage measurements - Alarms per channel--high limit, low limit, or both - Math functions--use Mx+B for custom linear conversions and converting raw inputs - Built-in thermocouple reference for temperature measurements (34921T) - Time-stamped readings - Add more formulas with BenchLink Data Logger Software The integrated DMM is mounted inside the mainframe and does not consume any of the eight user-available slots. You can access the DMM through any switch module that connects to the analog bus, or directly from the analog bus connector on the rear of the mainframe. The internal DMM gives you the lexibility to measure 11 types of inputs: - Temperature with thermocouples, RTDs, or thermistors (with 34921A) - DC and AC voltage - 2- and 4-wire resistance - Frequency and period - DC and AC current You can control the DMM directly, or conigure it to work in conjunction with the switches. Each switch channel can be conigured independently for measurement functions, scale factors and alarm limits. Advanced measurement features such as offset compensation, variable integration time, and delay are also selectable on a per-channel basis. The DMM inputs are shielded and optically isolated from the 34980A's earth-referenced circuitry and computer interface, and as a result, you get up to 300 V of input isolation. This is important for reducing ground-loops and common-mode voltage errors associated with long wiring runs and loating sources. Simple DMM calibration is accomplished with just the analog bus connection on the rear panel of the mainframe. You don't need to remove the mainframe from the rack or dedicate a channel for calibration. Modules provide lexible system stimulus and control System control--with analog outputs, open-collector digital outputs, clock generation, and isolated Form-C relays for controlling external devices. Additionally, with the microwave switch/attenuator driver, high-frequency switches and attenuators can be eficiently controlled external to the 34980A mainframe.

This is a convenient way to connect multiple test instruments to multiple points on a device under test. Choose from the following features: - Latching armature relays--300 V, 1 A - High-speed reed relays--150 V, 0.5 A - Conigurable dual 4x8, dual 4x16 or quad 4x32 modules - Single-wire coniguration (34933A or 34934A) - High density matrix with automatic surge protection and row disconnect for lexible measurements (34934A) - Analog bus expandable rows to create larger matrices (34931A, 32A, 33A) - Connections via standard 50 or 78-pin Dsub cables or detachable terminal block Figure 7. 34932A dual 4x16 armature matrix Each cross-point in the matrix switch has two wires--a high and a low for the measurement. Or, if you prefer, the 34933A and 34934A can be conigured as a single-wire matrix, increasing the number of channels. The 34933A also has in-rush resistors on each column for added protection. The 34934A also has in-rush protection resistors, but also has an automatic bypass switch for lexibility in making low-level measurements. Row disconnect switches also reduce the capacitance loading when combining modules to create larger matricies. Multiple matrix modules can be combined through the analog bus or the row expansion kit (34934A only) to create a larger matrix. The matrix can then be connected to the internal DMM for easy measurements. Combine your matrix with a multiplexer switch to achieve the desired switching topology and get a lower-cost solution with better speciications.

Bypassing resistors will reduce lifetime of relays. See the rated load relay life characteristics. [6] Limited to 6 W channel resistance power loss per module [7] Power restrictions allow only 20 channels to be closed at one time [8] Protection Resistors: 34933A - 100 5%; 0.5W; TC = 200ppm/C. 34934A - 100 1%; 0.25W; TC = 100ppm/C. If this resistance is not bypassed in the low side source line of a 4-wire resistance measurement, the 100 range is limited. [9] Channel resistance is typically < 1.5 but can go as high as 50 when a channel is used in measurement applications with < 10 mA load current. Increased relay channel resistance for measurements with load currents below 10 mA can occur on cards that have been out of service or following relay inactivity for periods of greater than 1 week. Switching relays for 2K cycles prior to use may reduce the variation in channel resistance. Applies to the 34931A and 34932A. Keysight recommends the use of 4-wire Ohms for resistance measurements. For high accuracy voltage measurements, select the DMM input resistance setting of > 10 G ohms to minimize the impact of relay contact resistance. 15 | Keysight | 34980A Multifunction Switch/Measure Unit - Data Sheet 34980A general-purpose switch modules The 34980A general-purpose switches can be used to route signals or to control other system devices.

It has eight 8-bit digital I/O channels with handshaking, pattern memory, two 10 MHz counters with gate functions, and a programmable clock output. Digital input/output The digital I/O bits are organized into two banks of 32-bits. The I/O bits can be conigured and programmed as inputs or outputs in 8-bit channels. The digital outputs can be conigured as active drive or open drain outputs with a 10 k pull up. User supplied pull up resistors for up to 5 V outputs are also acceptable. The digital inputs have programmable thresholds up to 5 V for compatibility with most digital logic standards. The onboard pattern memory can be used to select and output digital stimulus or bitstream patterns, or to capture external digital data. Each bank has independent memory and directional control so that one bank can output data while the other captures data. The memory can be divided up to 64 Kbytes per 8-bit channel. Speciically, the digital I/O channels also have: - Variable active high drive output from 1.65 V to 5 V or open drain - Variable input thresholds from 0 V to 5 V - Conigurable handshaking protocols including synchronous, and strobe - Programmable polarity - Source or sink up to 24 mA with a Imax of 400 mA per module. - Internal alarming for maskable pattern match - 1 hardware pattern interrupt per bank - Connections via standard 78-pin Dsub cables or detachable terminal block Frequency counter/totalizer The two channels can be used to count digital events, frequency, period, duty cycle, totalize, and pulse width.

Temperature within 1C of temperature at calibration (Tcal between 18-28C) [3] Relative to calibration standards [4] 20% over range on all ranges except 300VDC and AC ranges and 1 ADC and AC current ranges [5] For sine wave input > 5% of range; for inputs from 1% to 5% of range and < 50 kHz add 0.1% of range additional error; for AC filter slow [6] Typically 30% of reading error at 1 MHz, limited to 1 x 108 volt-hertz [7] Accuracy for 4-wire ohms. Add 4 ohms uncertainty (typ) for 2-wire ohms function due to conductor and contact resistance variability in the DMM. The 2-wire resistance accuracy can be improved by measuring a short on each channel and using the built-in y = Mx + b scaling function. See User Guide, Chapter 3. The series resistance of the 34923/24/25/33/34 limits the use of the 100 ohms resistance range. Keysight recommends the use of 4-wire ohms for resistance measurements. For high accuracy voltage measurements, select the DMM input resistance setting of > 10 G ohms to minimize the impact of relay contact resistance. [8] For inputs >100mV; for inputs 10mV to 100mV multiply % of reading error X 10; for 1 sec aperture (6 1/2 digits) [9] Specified only for inputs > 10 mA. For AC filter slow [10] Add 50 uV error for 34923A/24A/33A and 7 V error for the 34925A [11] Voltage measurements using Fixed-Z input impedance for the 100 V and 300 V ranges. 26 | Keysight | 34980A Multifunction Switch/Measure Unit - Data Sheet Additional Error for Frequency, Period (% of reading) Additional Low Frequency Error for ACV, ACI (% of reading) Frequency AC Filter Slow AC Filter Medium AC Filter Fast Frequency 1 second (61/2 digits) 0.1 seconds (51/2 digits) 0.01 seconds (41/2 digits) 0.73 3 Hz- 5 Hz 0 0.12 0.12 0.01 0.22 5 Hz - 10 Hz 0 0.17 0.17 0 0.18 10 Hz - 40 Hz 0 0.2 0.2 0 40 Hz - 100 Hz 0 0.06 0.21 100 Hz - 300 Hz 0 0.03 0.21 300 Hz - 1 kHz 0 0.01 0.07 > 1 kHz 0 0 0.02 10 Hz- 20 Hz 0 0.74 - 20 Hz - 40 Hz 0 0.22 - 40 Hz - 100 Hz 0 0.06 100 Hz - 200 Hz 0 200 Hz - 1 kHz 0 > 1 kHz 0 Aperture (Digits) 0 Temperature measurement accuracy Temperature coeficient/C Temperature 1-year accuracy Type Thermocouple (34921A only, includes cold junction accuracy on terminal block) B E J K N R S T 1100C to 1820C -150C to 1000C -150C to 1200C -100C to 1200C -100C to 1300C 300C to 1760C 400C to 1760C -100C to 400C 1.2C 1.0C 1.0C 1.0C 1.0C 1.2C 1.2C 1.0C RTD Ro from 49 to 2.1 K -200C to 600C 0.06C 0.003C Thermistor 2.2 k, 5 k, 10 k -80C to 150C 0.08C 0.002C [1] Extended range [1] Best range [1] 400C to 1100C -200C to -150C -210C to -150C -200C to -100C -200C to -100C -50C to 300C -50C to 400C -200C to -100C For total measurement accuracy, add temperature probe error; for <1C accuracy, an external fixed reference is required 1.8C 1.5C 1.2C 1.5C 1.5C 1.8C 1.8C 1.5C 0.03C 0.03C 0.03C 0.03C 0.03C 0.03C 0.03C 0.03C 27 | Keysight | 34980A Multifunction Switch/Measure Unit - Data Sheet Typical system speeds (Measurements made on a 3.2GHz PC running VB6 in Windows XP Pro) Single Channel Reading times in msec Direct measurements - direct to I/O (includes switch, measure time and I/O time) Direct measurement to memory(GPIB) USB 2.0 msec LAN (w/ VXI 11) msec Measurement into memory msec Single channel [1] [2] GPIB msec Single channel, DCV 2.83 3.14 4.57 1.90 Single channel, ACV 5.00 5.35 5.75 4.00 Single channel, ohms 2.91 3.14 4.65 1.90 Single channel while changing scale (eg MEAS DCV 10 / MEAS DCV 1) 9.52 10.64 11.76 8.40 Single channel while changing function (eg.

Data represented in this document are speciications unless otherwise noted. Characteristics describe product performance that is useful in the application of the product, but that is not covered by the product warranty. Characteristics are often referred to as Typical or Nominal values. - Typical describes characteristic performance, which 80% of instruments will meet when operated over a 20 C to 30 C temperature range. Typical performance is not warranted. - Nominal describes representative performance that is useful in the application of the product when operated over a 20 C to 30 C temperature range. Nominal performance is not warranted.
