1 Header
2 Frequency being measured, last RSSI reading, last measured BPS (in reverse video if >+-.5% of selected
speed, BER (count of bits in error in last received batch).
4 Header
5-8 Last 4 addresses captured and their message (if any). Most recent address is line 5, oldest on line 8.
7 (far right) GL if GPS is locked, ?? if GPS not locked or off.
8 (far right) % of ATA storage available for data (100 to 0, 100 meaning card empty, 0 meaning card is full of
data).
Note: ADDRESS is the address word defined in the POCSAG spec as a 21 bit number (18 bits sent over air, least significant
3 bits being the frame number (0-7)). The address displayed is the full 21 bit address (0-2,097,151).
MESSAGE is the first 18 character or digits associated with the address. The entire message (if > 18) is saved on the ATA card
and sent via RF DUMP.
POCSAG DECODE Measurements
1. BER/JITTER
Use this measurement to view RSSI, BPS and BER of a selected frequency. All address's and their messages (if any) are dis-
played in this measurement. BER,BPS, and RSSI are updated each time a batch is received. If no POCSAG data is detected on
the frequency selected, the RSSI is updated every second and BPS is displayed as'----.-'.
2. MATCH
Same as BER/JITTER but only address's and their messages that match an address in the address table are displayed. RSSI,
BPS, BER are updated as in BER/JITTER measurement. Both BER/ JITTER and MATCH save ALL data from all batches captured
on the ATA card and via RF DUMP if selected. The data saved is UN-CORRECTED (as received) for later analysis.
3. ENTER CAP CODE/VIEW CAP CODE
Use to enter the POCSAG pager addresses used in MATCH measurement. Enter table # (1-50) and press ENTER. The contents
of that table location will be displayed, 0000000 if empty. Enter the new address
and press ENTER. The screen will automatically step to the next table #. Just press enter to skip a table location, press ESC to
exit screen.
4. ERASE CAP CODES
Use to clear out all pager addresses in the address table (all
set to 0000000).
5. SELECT FC
Use this function to correctly set the POCSAG Function Code message types for the system being measured. Use the UP ARROW
key to select the message type (TONE ONLY, NUMERIC ONLY or ALPHA NUMERIC) associated with each function code (00,01,10
and 11). When all selections have been made, press the ESC key. The settings are saved in battery-backed RAM, so this pro-
cedure need only be done when changing to a frequency where the function codes are different.
The default setting as shipped from the factory for the function
codes is as follows:
