Parameter type
Discrete
OUTPut?
Response and default
The 3155 returns 1 if the output is on, or 0 if the output is off. Default value is 0.
OUTPut:FILTer{NONE|25M|50M|ALL}
Purpose
This command selects which filter is connected to the 3155 output. Observe the following restrictions when
you try to use this command:
1) Filter selection is not available when the instrument is set to output the standard sine waveform. In fact,
the default waveform shape is sine. Therefore, filter selection is available for use only after you select a
different waveform, or change the output mode to use.
2) Filters are placed before the output amplifier. Therefore, do not expect the filters to remove in-band am-
plifier harmonics and spurious.
•
NONE disconnects all filters from the output path
•
25M connects the 25 MHz low pass elliptic filter
•
50M connects the 50 MHz low pass elliptic filter
•
ALL connects both the 25 MHz and the 50 MHz filters in series
This subsystem controls the characteristics of the output. It controls
filter type and filter cutoff frequency. It is also used to control the sync
output, source and position. Optional nodes were omitted from these
commands. Factory defaults after *RST are shown in bold typeface.
Parameter low and high limits are given where applicable.
