Rx Signal
Level N/A 5 bytes Query Only.
Unit returns the value of the Rx signal level, in dBm, between –20 and
–60 dBm:
• If >-20dBm, returns RSL=GT-20 (GT means ‘greater than’)
• If in the range of –20 to –60dBm, returns RSL===-xx
• If <-60 dBm, returns RSL=LT-60 (LT means ‘less than’)
Example: RSL=== -45 (–45 dBm)
N/A RSL? RSL=xxxxx
(see Description of
Arguments)
Rx Symbol
Rate N/A 9 bytes,
numeric
Query only.
Returns the Rx symbol rate (shown on front panel), where in the form
