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 | |
| 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 | |
| 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. |
