An essential instrument
Thegenerationofpulsesforthestimulusandcontrolofelectronicsystems
isbeyond thecapability ofall butthe mostsophisticated offunction gener-
ators.
The architecture of a dedicated pulse generator enables it to generate
pulses of a set width regardless of the repetition rate offering duty cycles
which can extend down to 1 in 100 million.
Inadditiontocontinuousoperation,singleormultiplepulsescanbegener-
ated in response to trigger or gating signals with precisely defined timing
relationships.
A dedicated pulse-waveform output amplifier provides flat top pulses with
fast rise and fall times at variable amplitude.
Variable delay
The TGP110 offers selectable delay between the sync output and pulse
output. In triggered mode this also sets the delay between a trigger signal
and the start of the pulse.
Wide pulse range
TheTGP110cangeneratepulsewidthsintherange50nsto5s. Thereare
eight overlapping decade ranges with vernier control within each range.
The period range is 100ns to 10s, equivalent to a repetition rate range of
10MHz to 0.1Hz. Delay is independently adjustable over the same range
as pulse width.
A complement switch inverts the mark-space polarity.
Squarewave and double pulse
Insquaremode,squarewavesaregeneratedatafrequencysetbythepe-
riod controls alone. This provides a convenient means of generating vari-
able period edges where the pulse width is unimportant, for example.

justable.
SPECIFICATIONS
PERIOD, PULSE WIDTH, DELAY
Each parameter is variable within 8 overlapping decade ranges with a vernier
providing continuously variable control within each range.
PERIOD
Range: 100nsec to 10sec (10MHz to 0·1Hz).
Jitter: <0.1%.
PULSE WIDTH
Range: 50nsec to 5sec
Jitter: <0.1%.
DELAY
Range: 50nsec to 5sec
TRIGGER, GATE
RUN
Normal operational mode in which pulses are generated continuously at
0.1Hz to 10MHz.
TRIGGERED
DC to 10MHz pulse train in synchronism with external trigger pulses; pulse
width determined by pulse width controls. Trigger can be generated manually
from front panel button.
GATED
0·1Hz to 10MHz pulse train, parameters set by period and pulse width con-
trols, starts synchronously with leading edge of gate input. Last pulse is com-
pleted at the end of gating period. Gating signal can be generated manually
from front panel button.
PULSE MODES
NORMAL PULSE
One pulse is generated each period. The delay setting is ignored.
SQUAREWAVE
0·1Hz to 10MHz squarewave, frequency set by the period controls. Pulse
width and delay settings ignored.
Mark : Space ratio: 1:1 ±10%.
DOUBLE PULSE
A second pulse is generated after a delay set by the delay controls; the delay
is related to the leading edge of the first pulse.
DELAYED PULSE
A pulse is generated after a delay set by the delay controls; the delay is re-
lated to rising edge of the trigger signal.
INPUTS
GATE/TRIG INPUT
Frequency range: DC- 10MHz
Signal range: TTL threshold; max. input ±10V.
Min. pulse width: >30nsec.

nier.
Rise/Fall Times: Typically 10nsec into 50Ωload. Maximum 15ns.
