Arguments
for Command
(Note that all arguments are ASCII numeric codes from 48 to 57)
or Query
3 bytes Query only.
Returns the Number of stored Events, which remain Unread, in the
form xxx.
Note: This means unread over the remote control.
Example: >0001/NUE=126{CR}{LF}
3 bytes Query only.
Returns the Number of stored Statistics, which remain Unread, in the
form xxx.
Note: This means unread over the remote control.
Example: >0001/NUS=135{CR}{LF}
1 byte Command or Query.
Sets or returns the BERT Pattern in the form x, where:
0 = 2047
1 = Mark
2 = Space
3 = 1:1
4 = 1:2
5 = 2^15-1
6 = 2^20-1
7 = 2^23-1
8 = MIL-188
Example: <0001/PAT=0{CR} (sets 2047 Pattern)
5 bytes Query only.
When CnC is enabled and locked, returns the PSD ratio, in dB,
between the interferer and the desired signal power, in 0.1 dB steps.
Reporting format varies as follows:
Example 1: >0001/CPR=+02.8{CR}{LF} (interferer > desired)
(form=sdd.d, where: s = sign (+ / –), dd.d = value in dB)
Example 2: >0001/CPR=999.9{CR}{LF} (not locked or CnC not
enabled)
