Plug-in
The Plug-in function lists the model number, serial number, date, time, and
temperature delta. The temperature
∆
is the temperature change from the
temperature of the mainframe when the last calibration was performed. If this
temperature
∆
is greater than ±5
°
C since the last mainframe calibration, then
you must perform a plug-in module calibration to achieve the specified dc
accuracy.
Offset zero
The Offset Zero function performs a quick offset calibration on the optical
channel. Since the primary source of calibration error on the optical channel is
offset drift, this function is useful between the plug-in module vertical calibra-
tions if the plug-in module has not been removed or reinstalled and the oper-
ating temperature has not changed more than ±5
°
C. In order to ensure that
instrument specifications are met, perform the plug-in vertical calibration.
Performing an Offset Zero calibration is much faster than performing a com-
plete vertical calibration.

O/E cal
The plug-in module is provided with factory optical calibrations at 1310 nm
and 1550 nm. The O/E Calibration function allows you to calibrate the instru-
ment for use at one additional user-defined wavelength between 1000 nm and
1600 nm. This calibration does not affect the factory calibrations.
Calibrate probe
Connect a voltage probe to the plug-in and then press,
Calibrate probe
The analyzer calibrates to the tip of the probe by setting the probe attenuation
to the actual attenuation ratio of the probe. The analyzer also automatically
compensates for any offset the probe may introduce. The CAL signal is inter-
nally routed to the probe tip for Agilent Technologies probes.
