• Amplitude Measurement Range: −140 dBm to +30 dBm


• Amplitude Accuracy: ±0.5 dB (calibrated conditions)


• Noise Floor: −140 dBm or lower


• DANL: Typically −140 dBm/Hz at 1 GHz (varies with frequency and RBW)


• Resolution Bandwidth (RBW): 1 Hz, 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz, 1 MHz


• Video Bandwidth (VBW): 1 Hz to 1 MHz adjustable range

Key Features

• Multiple marker functions with configurable frequency, amplitude, and delta readouts


• RBW and VBW control for isolation of closely spaced signals and noise smoothing


• Trace functions including averaging, max hold, min hold, and normal display modes


• Amplitude correction for external component losses and flat-field response compensation


• Phase noise and spurious-free dynamic range performance suitable for adjacent channel power measurements and low-level signal detection

Typical Applications

• Research and development signal characterization


• Manufacturing quality control and acceptance testing


• Field service RF troubleshooting and diagnostic measurements


• Identification and analysis of unknown signals

Compatibility & Integration laboratory, manufacturing, and mobile field service environments. Supports external component integration through amplitude correction for cables, attenuators, and associated RF networks.
