Tomahawk Signal Strength Meter

The Tomahawk™ from Berkeley Varitronics is a battery-powered signal strength meter covering frequencies from 54.0 MHz to 805 MHz. It is ideal for the following applications:

• CATV
• Broadcast
• MMDS

Portable yet powerful, the Tomahawk is packed with an array of exceptional features.

• Small size (6.5" x 8.5" x 3.25") and weight (< than 3 lbs.)
• 9 channel measurements simultaneously presented in bar graph form (both audio and video carriers) for spectrum analysis
• 1 channel measurement that displays either audio or video carrier on a rolling x-axis graph.
• Keypad direct entry or rotary dial contro for quick tuning.
• Internal 15 volt phantom power provided for MMIDS down-converter alignment or field strength measurements.
• RS-232 interface for post processing, report generation or logging, as well as quick auto calibration.
• Continuous operation for more than 2 hours.
