GATING MODES
Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector.
The instrument can be set to stop triggering when this input high or low, using the front-
panel gate menu or the appropriate programming commands. When gated, the output
will complete the full pulse width if the output is high, and then stop triggering. Pulses
are not truncated.
OPERATION AT LOW AMPLITUDES
This instrument will generate the best waveforms when operated near maximum
amplitude. If amplitudes less than ~ 20% of the full-scale value are desired, better
results will be obtained if the pulse generator is operated at a higher amplitude, and an
attenuator is connected to the output.
Avtech recommends the BW-SxxW2+ series of 18 GHz coaxial attenuators from Mini-
Circuits,
. (The “xx” in the part number is replaced with the
numeric attenuation value in dB).
