Site Master Returns: 1 byte

1)255 (FFh) Operation Complete Byte

224 (E0h) Parameter Error: Not enough bytes transferred

225 (E1h) Memory Error: Not enough memory to store data 238 (EEh) Time-out Error

Notes:

return loss = - 20* ( log(Gamma) / log(10) ) VSWR = (1+Gamma)/(1-Gamma)

Phase compares the reflected to the incident (reference)

Query System Status – Control Byte #29 (1Dh)

NOTE: This command is new to the S33xD. Use it instead of Control Byte #20 to access new features.

Description: Queries the Site Master for current system settings. Unlike Control Byte #20, this command returns only data that is valid for the active mode, plus system settings, such as the defined printer.

The current state of the Site Master represents the state after the last successful remote control operation. For example, change the start frequency to another valid frequency while in remote mode, then execute control byte #29. The new start frequency will be returned in the defined bytes, even though no sweep has been performed with that frequency.

Bytes to Follow: 0 bytes

Site Master Returns:

For All Modes:

81Gamma data uses 1/1000 units.

82Phase data uses 1/10 degree unit.
