external equipment. “Input” allows an external time base signal applied to the 10 MHz Ref In/Out
connector to be routed into the R8100.
Analog Measurement Averaging
Enables measurement averaging to smooth selective analog readings. Analog Measurement Averaging
affects the following:
RF Zone – Frequency Error; Deviation
Display Zone – Frequency Error Bar Graphs; Deviation Bar Graphs
Meter Zone – AC Volts; DC Volts; Internal Distortion; External Distortion; SINAD
Analog Averaging Samples
Sets the number of samples used from 2 to 100 when Analog Measurement Averaging is enabled.
Digital Measurement Averaging
Enables measurement averaging to smooth selective digital readings. Digital Measurement Averaging
affects the following:
DMR Zone – Symbol Deviation, FSK Error; Magnitude Error
PROJECT 25 Zone – Symbol Deviation, Modulation Fidelity
P25 Trunk Zone – Symbol Deviation, Modulation Fidelity
NXDN™ Zone – Symbol Deviation, Modulation Fidelity
TETRA Zone – Averaging is controlled locally; see 2.2.7.7.1.2
Digital Averaging Samples
Sets the number of samples used from 2 to 100 when Digital Measurement Averaging is enabled.
Pre-Amplifier Auto Off
When enabled (default), the R8100 automatically switches off the Pre-Amplifier to maintain measurement
accuracy when broadband RF power measurements are selected or detected. A message appears for
several seconds informing the user that the Pre-Amplifier will be turned off. If a user chooses to override
the setting an alert is displayed as shown in Figure 3.2.9.2-2.
