DC_OFFSET

(IEEE-488, RS-232, Overlapped, Coupled)
Applies a dc offset to an ac signal in WAVEGEN mode only.
Parameter:

Offset amplitude with optional multiplier and voltage unit.

Example: DCOFFSET

1.44

MV.

DC_OFFSET?

(IEEE-488, RS-232)
Returns the dc offset voltage.
Response:

(Float) signed offset amplitude.

Example: +1.44E-03 (1.44

mV)

+0.00E-03

(No dc offset)

EDIT

(IEEE-488, RS-232)

(Edit command) Sets the edit field. PRI is specified for the output value in single output
functions and the primary output value in dual output functions. SEC is specified for the
secondary value in dual output functions. FREQ is specified for the frequency in single
ac output functions. The frequency cannot be edited in dual ac output functions. EDIT
OFF is the same as using the NEWREF command.

Parameters: PRI

(edit the value in single output functions and the pulse width in

PULSE

mode)

SEC

(edit the pulse period in PULSE mode)

FREQ (edit the frequency value in single ac output functions)

OFF

(edit is off, which is the same as using the NEWREF command)

Example: EDIT

FREQ

Load FREQ into the edit field to edit frequency.
