8 Specifications
Unless otherwise stated, specifications are valid for an ambient temperature range of 0
to 70°C (or -40 to +85°C for option 1), image rejection on, amplitude of signal applied
less than the reference level.
8.1 Frequency
Frequency Range: 1 Hz to 4.4 GHz
Span Modes: (Center Frequency + Span) or (Start + Stop Frequencies)
Maximum Span: 4.4 GHz
Minimum Span: 10 Hz or Zero Span
Internal Frequency Reference Accuracy: ±1 ppm
For greater frequency accuracy connect to external 10 MHz timebase (0 to +20 dBm)
Frequency Readout Accuracy: reference error ±1 sample
Marker Accuracy: reference error ±1 sample
Resolution Bandwidth: 0.1Hz to 250KHz and 5MHz
Spectral Purity
Residual FM, 3KHz Audio LPF, 15 KHz IF BW: [0.1 Hz + 4 Hz / GHz] typical RMS
FM (e.g. 2 GHz RF would have 8.1 Hz RMS FM). Increasing IF BW increases residual
FM.
Note 1: 1 sample represents approximately 40% of the selected RBW
Note 2: 5 MHz RBW accuracy not specified, software support coming soon
8.2
Amplitude (RBW ≤100KHz)
Range: 1dB Gain Compression to Displayed Average Noise Level (DANL)
1dB Gain Compression: (attenuator set to 15dB, preamp off)
+16dBm Typical, 1Hz to 150MHz
+19dBm Typical, 150MHz to 4.4GHz
Displayed Average Noise Level: 0dB input attenuation, 1Hz RBW
