Max. current
50 mV to 2 V per step, 6 steps, 1-2-5 switching
±40 V
At least 500 mA at 8 V or less, at least 200 mA at 15 V,
at least 10 mA at 40 V
Step 1/10 1/10 times of step current/voltage setting value
Step rate 50 Hz or 60 Hz × 2
( × 1 when collector supply mode is set to AC)
Pulse interval setting when collector supply is set to HC mode.
Pulse step
Pulse width 50 us to 400 us (in 10us step)
When collector supply is in HC mode, pulse width is wider than
that of the HC mode pulse; i.e., additional 100 us at each end
Note: If the pulse width is narrow, to max. peak voltage may not
be generated.
No. of steps 0 step to 20 steps
AUX output
Range Off, − 40 V to + 40 V, 100 mV step
Accuracy 100 mV + 2 % of setting value
Measurement
Mode REPEAT, STOP/SINGLE, SWEEP
