Automatic Amplitude Discrimination
Automatically measures the largest of all signals present, provided that signal is >6 dB (typical) above any signal within
500 MHz ; >20 dB (typical) above any signal within 500 MHz to 26.5 GHz.
Tracking Speed
Resolution = 1 Hz, Speed = 1 MHz/sec
Resolution = 10 kHz, Speed = 1 GHz/sec
Acquisition Time
Resolution = 1 Hz, Time = <125 ms
Resolution = 10 kHz, Time = <60 ms
Maximum Deviation
20 MHz p-p, Automatic mode
60 MHz p-p, Manual mode (via HP-IB only)
Maximum FM Rate: 10 MHz
AM Tolerance: Any modulation index provided the minimum signal level is not less than the sensitivity specification.
Power Meter Specifications
Frequency Range: 0 MHz to 26.5 GHz, sensor dependent
Power Range: -70 to +20 dBm (100 pW to 100 mW), sensor dependent
Dynamic Range: 50 dB in 10 dB steps
Resolution: 0.01 dB in logarithmic mode, 0.1% of full scale in linear mode.
Auto Filter: The meter automatically selects the required number of averages for the selected range.
Accuracy
Instrumentation: ±0.02 dB or ±5%
Zero Set (digital settability of zero): ±5% of full scale on most sensitive range. Decrease percentage by a factor of 10
for each higher range, ±1 display count.
