Chapter 5. SERIAL-BASED REMOTE PRODUCT
5.1
Overview
This chapter describes the protocol and message command and query set for complete remote monitor and control of the HPOD SSPA. It
also summarizes key operational parameters and some of their most commonly‐used remote commands and queries.
5.2
Key Operational Parameters
See Sect.5.5 Remote Commands and Queries for detailed information about the remote commands and queries mentioned
in this section.
5.2.1 RF Input Level
The individual amplifier maximum gain and power rating determines the RF input level required to reach the full rated output power of
the HPOD.
For example: If the test data of an SSPA rated for 250W (54 dBm) indicated a gain of 75 dB, then a signal of 54dBm – 75 dB = ‐21 dBm
would approximately give the rated output power.
Increasing input power beyond this level results in an output signal with increasingly higher levels of distortion. Of course, if the SSPA
attenuation control is utilized, a higher‐level input signal level can be accommodated.
