Input Impedance

The impedance can be set to 50 ￿ or 1 M￿.

Parameters

MIN or <Decimal data> that rounds off to 50 or less, sets the input impedance to 50 MAX or <Decimal data> that rounds off to 1001 or more, sets the impedance to 1 M￿.

Returned format:

Example for Input A (1)

SEND￿ :INP:IMP ￿ 50

Sets the input A impedance to 50 ￿.

Example for Input B (2) (Only for PM6680B/81)

SEND￿ :INP2:IMP ￿ 50

Sets the input B impedance to 50 ￿.

*RST condition 1 M￿

Complies to standards: SCPI 1991.0, confirmed.

Fixed Trigger Level

Input A and input B can be individually set to autotrigger or to fixed trigger levels of between –5 V and +5 V in steps of 0.02 V (1.25mV for PM6681). If the attenuator is set to 10X, the range is –50 V and +50 V in 0.2 V(12.5mV steps).

For autotrigger, see the following page.

Parameters: <Decimal data> is a number between –5 V and +5 V if att=1X and between –50 V and +50 V if att=10X.

MAX gives +50 V and MIN gives –50 V

When using MAX and MIN as data, the counter always tries to set the trigger level to +50 V and –50 V. If the attenuator is set to 1X, it is impossible to set this trigger level, and the counter will return an error message.

Returned format: <Decimal data>￿

Example for Input A (1)

SEND￿ :INP:LEV ￿ 0.01

Example for Input B (2)

SEND￿ :INP2:LEV ￿ 2.0

*RST condition 0 (but controlled by Autotrigger since AUTO is on after *RST)
