Setting Up Pager The following steps are required to set up pager encoding on the
Encoding signal generator. Details of setting each parameter are provided
following this overview.
la-26 Operation Examples
1. Before entering the signal generator pager encoder mode,
set the correct carrier frequency and FM deviation for the
pager-under-test. (The FM deviation is 4.8 kHz for FLEX and is
4.5 kHz for POCSAG.)
2. Press [-ON/OFF_) to turn on the RF output. (RF OFF is displayed
below the amplitude setting when the RF output is turned off.)
3. Enter the pager encoder mode by pressing m (ENCODER). If FM
wasn’t the last active function, press (FM) (ENCODER) twice.
4. Set up the pager encoder parameters to meet the test requirements
of your specific pager.
Use the (IJ (NEXT) and @) (PREV) keys to scroll through the
encoder parameters. The cursor will blink around the first letter
of the active parameter. The @J (NEXT) key moves forward
sequentially through each pager encoder parameter and the
@‘j (PREV) key moves backward sequentially.
To move between settings for each parameter, rotate the
AMPLITUDE/ENCODER knob until the desired setting is
displayed. When characters are entered by way of the keypad
(such as the capcode), terminate the entry with the (jjdB(mL)
(ENTER) key.
5. Start signaling the pager after all of the encoder parameters are set
by pressing the (jj] (START/STOP) key.
