Anritsu ML2430A operation manual +/- key on the numeric keypad allows selection of a user

SENSOR MENU OPERATION

NOTE

Whichever set, or sets, of cal factors are used, the linearity and tem- perature correction re- mains active at all times. Ensure the power meter is pro- grammed with the fre- quency of the signal being measured.

NOTE

Manual Cal Factor method only.

	Factory
	Selects the Factory calibration factor table. Pressing Factory and
	the +/- key on the numeric keypad allows selection of a user-
	defined table in addition to the factory table. This allows full factory
	calibration to be active, and allows adjustments or corrections to be
	entered in the user-defined table. If user table 1 was selected, the
	menu would show ‘Factory+1’ and the Status box on the readout
	display would show a warning ‘*’ sign on the Cal Factor line (bottom
	text line in the box) to show that non-standard calibration is being
	applied (CAL *F or CAL *V).
	Enter
	Confirms the selection.
%/dB	Toggles the Current Cal factor display format from percentage to
[CFUNITS]	dB, and back.
EDIT	Edit any of the available user calibration factor tables in the sensor.
[CFUADD	Options available are CLEAR or PRESET the table, enter a new ta-
CFUSAV	ble identity string, change or delete existing frequency/cal factor
CFUCT	data pairs, or enter new frequency/cal factor data pairs. All fre-
CFUPT
	quency/cal factor data pairs can have both frequency and calibra-
CFULD
	tion factor value modified, except for the data pair at 50 MHz, which
CFURD
	can only have its cal factor value changed. All frequency/cal factor
CFUID]
	data pairs can be deleted, but there must always be one data pair
	remaining. If there is a data pair at 50 MHz, this will be the data pair
	that will remain.
	The user must ensure that the maximum number of cal factor data
	pairs entered into a table is not exceeded. Sensors with a maxi-
	mum frequency of up to 40 GHz will hold 90 pairs, while sensors
	with a maximum frequency of 50 GHz will hold 110 pairs.
	Once all changes have been made, the SAVE soft key saves the
	changed data to the sensor. If any user cal factor data is changed
	and not saved, any attempt to exit the cal factor menu or select a
	new table will result in a prompt to discard or save the changes.
FACTOR	When the Cal Factor Source is set to Manual, the operator is ex-
[CFCAL]	pected to enter the calibration factor value in dB or % terms.
CAL	Sets a calibration factor to be used when performing a 0 dBm cali-
ADJUST	bration and the calibration factor source is set to 'Manual.' This
[CFADJ]	value is the only factor applied when performing a 0 dBm reference
	calibration. If the sensor calibration factor source is set to V/GHz or
	Frequency, the sensor internal EEPROM correction value at 50
	MHz is used.
