ITPROGFILTBANK

Allowable filter configurations

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

The ITPROGFILTBANK log provides information on the allowable configurations for the programmable filter for each frequency when applying either a notch filter or bandpass filter. The current filters in use can be seen with the ITFILTTABLE log.

For dual antenna receivers, an ITPROGFILTBANK_1 log can be requested to view the allowable configurations for the second antenna. As described in Table: Binary message header structure, the message type indicates the log is from the second antenna. To request an ASCII log enter ITPROGFILTBANKA_1, and for a binary log enter ITPROGFILTBANKB_1.

The ITPROGFILTBANK and ITPROGFILTBANK_1 logs use the same message ID.

Message ID: 2023

Log type: Asynch

Recommended input:

log itprogfiltbanka once
