Amplitude Power in dBm
Signal-to-noise Ratio 55 to 65 dB (typical). Noise floor can be
reduced by increasing the number of points in the FFT.
Sensitivity Range 1 dBnv/div to 100 dBni/div
Dynamic Range 55 to 65 dB (typical)
Offset Range —200 dBm to +200 dBm
Notes:
1) The gain accuracy decreases 0.08% of full scale per °C from the firmware
calibration temperature. This characteristic is valid for a temperature range +10°C
from the firmware calibration temperature. The characteristic applies to both modes;
repetitive and real time (single acquisition).
2) Expansion is used below 7 mV/div range so vertical resolution and accuracies are
correspondingly reduced. Below 7 mV/div full scale is defined as 56 mV.
3) The available waveform record length over HP-IB is 32,768 points in the real-time
mode and 500 points in the repetitive mode.
