Reference level

Range

Log +30.0 to -99.9 dBm or equivalent in dBmV, dBµV, volts. Readout expandable

to +60.0 dBm to -119.9 dBm (-139.9 dBrn for < 1 kHz RBW)

Linear 7.07 V to 2.2 µV full scale. Readout expandable to 223.6 V to 2.2 µV

(0.22 µV for < 1 kHz RBW)

Accuracy

The sum of the following factors determines the accuracy of the reference level readout.

Measurement technique used after calibration with CAL signal determines applicability of

uncertainty sources. Specifications given with preselector tracking optimized using

MARKER PRESELECTOR PEAK.

With corrected readout (SHIFT W and SHIFT X executed just prior to measurement), 20 °

to 30 °C temperature range, and minimum one hour warmup time.
