Status Commands

The instrument status model can be controlled, and its current state
queried, using commands from the SCPI STATus subtree. All the STATus
commands available for the 8156A attenuator are supported by the
81560A/1A/6A/7A modular attenuator familiy except:
STATus:OPERation:PTRansition
STATus:OPERation:NTRansition
STATus:QUEStionable:PTRansition
STATus:QUEStionable:NTRansition
There are new status bits available to query the current modular
attenuator state.

User Calibration Data

The user calibration mode of the 8156A overrides the attenuator's built-in
wavelength calibration table, so allowing user defined wavelength
compensation. Since the 81560A/1A/6A/7A modular attenuator family
features an improved factory calibration process, so this user calibration
feature (page 123) is not supported.
The 81560A/1A/6A/7A modular attenuator family includes a user
configurable offset function. If you enable this feature, the module's
internal wavelength compensation remains active and you are able to
compensate for additional external wavelength-dependent losses within
the measurement setup by creating a wavelength/offset table. For
additional information, refer to our Application Note "Variable Optical
Attenuator in BER Test Applications", part number 5988-3159EN.
