Chapter 5. SERIAL-BASED REMOTE PRODUCT

MANAGEMENT

5.1

Overview

Serial-based remote product management of Comtech EF Data’s SPOD family of Outdoor Amplifiers is available using the SPOD’s ‘J6 |

COM 1’ port. Some key parameters and procedures and their associated remote commands and queries are summarized, followed by

detailed instructions for use of the serial remote control communication command and query interface.

Key Operational Parameters

For detailed information about the remote commands and queries mentioned in this section, see Sect. 5.4 Remote Commands and

Queries in this chapter.

5.2.1

RF Input Level

The required RF input level to reach the full rated output power of the SSPA is determined by the individual amplifier maximum gain and

power rating.

For Example: If the test data of an SSPA rated for 250W (54 dBm) indicated a gain of 75 dB, then a signal of 54 dBm – 75 dB = -21 dBm

would approximately give the rated output power. Increasing input power beyond this level would result in an output signal with

increasingly higher levels of distortion. Of course, if the SPOD Attenuator Control is utilized, a higher level input signal level can be

accommodated. The maximum input level should never exceed 15dBm, or permanent damage to the unit may occur.
