Parameter Definitions

Parameter # of bytes Step Example / Description

Frequency 4 bytes unsigned 1 Hz 1000.3 MHz = 1000300000

Scale (RL, CL) 2 bytes unsigned 1 / 1000 dB 51.3 dB = 51300

(SWR) 2 bytes unsigned 1 / 1000 (ratio) 65.53 = 65530

Limit (RL, CL) 2 bytes unsigned 1 / 1000 dB 51.3 dB = 51300

(SWR) 2 bytes unsigned 1 / 1000 (ratio) 65.53 = 65530

Markers (frequency and

distance marker)

2 bytes unsigned 1 sweep point

Marker values are given in relative position of the graph. The

lowest value is 0, the highest is (# of data points –1).

Distance 4 bytes unsigned 1/100,000 m/ft 12.34 m = 1234000

Relative Propagation Velocity 4 bytes unsigned 1 / 100,000 0.837 = 83700

Cable Loss 4 bytes unsigned 1 / 100,000 dB -0.345 dB/m = 34500

Gamma 4 bytes signed 1 / 10,000 (ratio)

Gamma value is the ratio of magnitude of the reflected signal over

the magnitude of the incident signal.

Phase 4 bytes signed 1 / 10 degree

Phase value is the difference in phase between the incident and

reflected signals.

Power: dBm/dB 4 bytes signed

1 / 1000 dBm

1 / 1000 dB

51.3 dBm = 51300

10.4 dB = 10400

Lock Fail Counter 2 bytes unsigned 1 error count 234 fails = 234

Integrator Fail Counter 2 bytes unsigned 1 error count 123 fails = 123
