B.22 Tektronix Stimulus System HFS9000 (Berlin W-Band)

Module name: hfs9000

Description: Tektronix Stimulus System HFS9000, used as pulser in the Berlin W-band spectrometer. No support for phase cycled experiments.

Timebase: between 1.6 ns and 20 us
Maximum pulse voltage: between -1.5 V and 5.5 V
Minimum pulse voltage: between -2 V and 5 V
Difference must be not more than 5.5 V and at least 0.5 V
Resolution of pulse voltages: 10 mV
Trigger-in levels: between -4.7 V to 4.7 V
Resolution of trigger-in voltages: 10 mV
Number of channels: 4 plus a TRIGGER_OUT channel
Fixed length of TRIGGER_OUT pulse: 20 ns

Controlled via: GPIB bus (IEEE 488).
In the GPIB configuration file use "HFS9000" as the device name, '\n' or 0xa as the EOS character, set set-reos and set-xeos to no and set-bin to yes.
