72-6860 - 10MHz Pulse Generator
10MHz Pulse Generator
Unlike conventional function generators, a dedicated pulse generator is able to generate pulses of a set width, regardless of the repetition rate, offering duty cycles which can extend down to 1 in 100 million. In addition to continuous operation, single or multiple pulses can be generated 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.
The Tenma 72-6890 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
The Tenma 72-6890 can generate pulse widths in the range 50ns to 5s. There are 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.
Square Wave and Double Pulse
In square mode, square waves are generated at a frequency set by the period controls alone. This provides a convenient means of generating variable period edges where the pulse width is unimportant.
In double pulse mode, a second pulse is generated within every period at a set delay after the start of the first pulse. The delay is independently adjustable.

PERIOD, PULSE WIDTH, DELAY
Each parameter is variable within 8 overlapping decade ranges with a vernier providing continuously variable control within each range.
Normal operational mode in which pulses are generated continuously at 0.1Hz to 10MHz.
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.
0.Hz to 10MHz pulse train, parameters set by period and pulse width controls, starts synchronously with leading edge of gate input. Last pulse is completed at the end of gating period. Gating signal can be generated manually from front panel button.
One pulse is generated each period. The delay setting is ignored.
0.1Hz to 10MHz square wave, frequency set by the period controls. Pulse width and delay settings ignored.
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.
A pulse is generated after a delay set by the delay controls; the delay is related to rising edge of the trigger signal.
