Anritsu ML2430A operation manual User CAL Factors, Readout Mode

USER CAL FACTORS PROCEDURES

Cal factor tables are accessed through the SensorCalFactorUSE TABLE front panel menus (Chapter 4), or through GPIB commands (Chapter 6).

Example Procedure	Use the key sequence SensorCal FactorEDIT to get to the table edit menu. Use
	the TABLE key to select the table, then the EDIT key to edit that table. Press the
	INSERT key to enter frequency and cal factor data pairs.
	For example, in order to enter the frequency/cal factor pairs 1 GHz @ 100%, 2
	GHz @ 101%, 3 GHz @ 98% and 4 GHz @ 98%, step through the keys in the
	following sequence:
	FREQ, 1, GHz.Entr
	FACTOR, 100, %
	FREQ, 2, GHz. Entr
	FACTOR, 101, %
	FREQ, 3, GHz. Entr
	FACTOR, 98, %
	FREQ, 4, GHz. Entr
	DONE
	The frequency/cal factor pairs can be entered in any order. Each time a new fre-
	quency is entered, a new data pair is formed. As the data pairs are entered, they
	are sorted into frequency ascending order.
Readout Mode	In Readout mode, the bottom text line in the Status box indicates what type of
	calibration factors are being used. At any time, if anything other than the factory
	supplied cal data is applied, the Status box display shows a warning ‘*’ sign on
	the Cal Factor line to show that non-standard calibration is being applied. For
	example:
	CAL F = frequency cal factors using factory defined table
	CAL V = volts per GHz cal factors using factory defined table
	CAL M = manual cal factor
	CAL *F = frequency cal factors employing a user defined table
	CAL *V = volts per GHz cal factors employing a user defined table
	This is because the application of user cal factors can completely change the
	calibrated response of the Sensor.
