Signal Conditioning Measurement Operations & Settings
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 167
Display and System Commands
The commands to adjust the instrument display (page 104ff) and query the
error queue (page 122) also work with the 816xA/B platform:
DISPlay:BRIGhtness
DISPlay:ENABle
SYSTem:ERRor?
IEEE Commands
Every SCPI compatible measurement instrument implements a subset of
the IEEE SCPI command set. The 8156A attenuator and the
81560A/1A/6A/7A attenuator family use almost the same subset. The
following IEEE commands are available when using the 8156A but not
available when using the 81560A/1A/6A/7A modules (page 93ff):
*RCLRecover parameter setup
*SAVSave parameter setup
*SRE and *SRE?Status request register
OUTPut:APMode?
It is now possible to adjust both power and attenuation without changing the
mode, so this command is supported only to address compatibility issues. This
query returns whether power (1) or attenuation (0) was changed last. All other
actions have no effect on this internal flag.
OUTPut:POWer
Except that the base power level is determined in another way (see OUTPut:AP-
Mode), there is no change to the semantic of this command.
OUTPut:POWer?
No change.
OUTPut:STATe
No change.
OUTPut:STATe?
No change.
OUTPut:STATe:APOWeron
No change.
OUTPut:STATe:APOWeron?
No change.
