• A boost suppression option to assess whether certain signals are internally generated or actually present in the input signal.


• After a small HW modification, demodulated audio can be listened to.

High input mode specification:

• Input frequency range from 240MHz to 960MHz.


• The input impedance depends on the frequency and varies from 50 ohms.


• Since there is no input bandpass filter, strong input signals outside the 240-960 MHz range can distort the bandpass signals.

• Frequency accuracy equal to the selected resolution bandwidth.


• Activate free dynamic range when using 30 kHz resolution bandwidth of 50 dB.


• Manually selectable resolution filters 3, 10, 30, 100, 300, 600 kHz. Automatic selection of one of 57 resolution filters.


• A frequency-dependent input attenuator is selectable from 25 dB to 40 dB. The power level error increases to +/- 10 dB when this attenuator is activated.


• Screen resolution 51, 101, 145 or 290 measurement points.


• Scanning speed exceeds 1000 points/second using the highest resolution filters.


• Automatic optimization of actual scan points to ensure coverage of the entire scan range, regardless of the bandwidth of the selected resolution.
