Cal factor tables are accessed through the Sensor|CalFactor|USE TABLE front

panel menus (Chapter 4), or through GPIB commands (Chapter 6).

Example Procedure

Use the key sequence Sensor|Cal Factor|EDIT 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.
