Table C-2: Calculating the parameters required for test command 101
Calculating parameters for test command
101
Enter the parameters in the format tttttt T rrrrrr R F
■
tttttt represents the transmit frequency
See Example 1
■
T and R represent channel spacing
0 = 5 kHz
1 = 6.25 kHz
■
rrrrrr represents the receive frequency
See Example 2
■
F indicates whether the test command changes
the calibration values
0 = do not change calibrated values
1 = recalculate the calibrated values based on
new frequencies
Note: tttttt and rrrrrr may be up to 6 digits long.
Example 1: Calculating tttttt for an H band
radio
Example 2: Calculating rrrrrr for an H band
radio
Note: IF depends on the radio’s switching band.
■
For A, B, C and D bands radios, the IF is 21.4 MHz.
*(For A band, add the IF (MHz) in the formula (radio
uses high side injection).)
■
For E, F, G, H, I, J and K band radios, the IF is
45.1 MHz.
