Introduction
The ST5120 hand-held Field Strength Meter uses RF signal processing techniques in
combination with microprocessor technology to produce quick and accurate signal
measurements. The meter provides the user a choice of reading individual channel video,
audio, or a-a power level measurements. Automatic/semi-automatic internal calibration
corrects for measurement variations due to frequency response, temperature change and
internal attenuator setting. The combination of keypad tuning and menu driven display
allow for simple operation.
The meter is programmed with both USA CATV and UHF/UHF NTSC standard formats.
Users can also select frequencies for signal testing. The backlit LCD allows for viewing
signal measurements even in dark places.
