Using The Instrument 3-9
The command:
VOLTage:OFFSet <offset>
sets the offset for the currently active function. The default offset is
0 V.
The query:
VOLTage:OFFSet?
queries the output offset for the currently selected function and
returns a value in volts.
Selecting the Filter
Type
Before selecting the filter type, use the following command to
activate the filter:
OUTPut:FILTer { OFF | ON}
ON enables the filter that has been selected with the
OUTP:FILT:FREQ command. The default filter state setting is OFF.
The query:
OUTPut:FILTer?
queries the output filter state and returns "0" (OFF) or "1" (ON).
The command:
OUTPut:FILTer:FREQuency {<20MHz | 25MHz |
50MHz>}
sets the filter frequency for the currently active function. 20 MHz has
a Gaussian response, and the 25 MHz and the 50 MHz filters have
an Elliptical response. Note that the filters cannot be changed if the
synthesizer is set to output sine waveform from its standard
waveform library. The filters will be activated only after the
OUTP:FILT ON command. The default filter setting is 20 MHz. Note
also that 20 MHz, 25 MHz and 50 MHz designate filter types. These
parameters should be programmed as switches, not as values. The
filter type cannot be programmed using OUTP:FILT:FREQ 25e6 or
OUTP:FILT:FREQ 50e6 Hz.
The query:
OUTPut:FILTer:FREQuency?
queries the currently selected filter setting and returns 20 MHz, 25
MHz or 50 MHz.
