PM6685

Waveform compensation

The three-position waveform compensation on the front panel is not available from the bus. Instead, you can set the trigger level, that is, the level on which the hysteresis band is centered. How to set the trigger level depends on the duty cycle and the peak-to-peak voltage of the signal.

Trigger level ￿ Vpp * (0.5 ￿ Duty factor )

This setting has no effect unless autosensitivity is turned off, see the following page.

Parameters

<Decimal data> is a number between approximately –37.7 V and +37.7 V.

MAX gives +37.7 ... V and MIN gives –37.7... V

Note that the ￿ :INP:LEV command is coupled with the :INP:HYST command. See page 9-45.

Returned format: <Decimal data>￿

Example:

SEND￿ :INP:LEV ￿ 3.75;LEV:AUTO ￿ 0

This example sets the trigger level to 3.75 V and switches off auto trigger level. *RST condition 0 (but controlled by Autotrigger since AUTO is on after *RST)
