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.
