I haven't used that particular model, but I believe you can.
I have made many experiments with other meters to confirm it.
A signal level meter designed for analog (NTSC) signals can have a digital meter readout or an analog panel meter readout. The newer meters for digital (ATSC 8vsb and QAM) signals have a digital meter readout.
The meter is called wavetek sam 3 Digital signal analysis meter.
The top middle has a scale changeable from -15 to +55 db and also has a frequency in Mhz digital display to the right. Worked great on tv frequency but can't check out channels because the battery died. It will cost a few dollars to replace it. Will this meter work? If so I'll get a new battery.
