USE TABLE [CFUSEL, CFUTBL, CFUUSE, CFUVLD]
Defines which calibration factor table is to be used. Can be set to Factory, table number
1-10, or Factory + table number. The maximum number of tables available is displayed
on the screen, and is never greater than 10. If a selected table has not been used before,
the user will be prompted to CLEAR or PRESET the table, or cancel the selection. If a
table is CLEARED, all entries are cleared except for a single entry of 100 % @ 50 MHz.
If a table is PRESET - the factory defined calibration factor table is copied into the
specified user calibration factor table. The CLEARED or PRESET table is saved
directly to the sensor. PRESET clears the ID string, while CLEAR leaves the ID string
as currently set.
The number of tables available is defined by the frequency range of the sensor and the
amount of factory calibration data stored.
%/dB [CFUNITS]
Toggles the Current Cal factor display format from percentage to dB, and back.
EDIT [CFUADD, CFUSAV, CFUCT, CFUPT, CFULD, CFURD, CFUID]
Edit any of the available user calibration factor tables in the sensor. Options available
are CLEAR or PRESET the table, enter a new table identity string, change or delete
existing frequency/cal factor data pairs, or enter new frequency/cal factor data pairs.
All frequency/cal factor data pairs can have both frequency and calibration factor value
modified, except for the data pair at 50 MHz, which can only have its cal factor value
changed. All frequency/cal factor 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.
Note
User defined Cal Factor tables are available for applications where user-supplied
calibration points are required. Additional cal factor frequencies can be entered in
a user table and used in conjunction with the factory table.
Delete: Deletes the currently displayed table number.
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.
Note
Whichever set, or sets, of cal factors are used, the linearity and temperature
correction remains active at all times. Ensure the power meter is programmed with
the frequency of the signal being measured.
