Digital channels: From 35 to 120 dBμV (-25 dBmV to 60 dBmV)

(channels of 8 MHz).


Maximum input level

From 5 to 863 MHz: 120 dBμV (60 dBmV)

DC to 60 Hz: 60 V DC or RMS

Reading: Digital in dBµV, dBmV or dBm and analogue

by Graphic display with backlight.

1 dB resolution.


Accuracy

Analogue Channels: ± 2 dB (0 to 40 °C) Negative video modulation

Digital Channels :± 3 dB (0 to 40 °C) For 8 MHz channel

bandwidth


Digital measurements
