257 Series Automatic Modulation Meters

Simplify the measurement of amplitude and frequency modulation on signals in the range 1.5 MHz to 2 GHz. By eliminating the need to tune a local oscillator and make level adjustments, the 257 speeds up measurements and reduces errors. Patented circuitry ensures that the meter always locks to the strongest signal available ignoring spurious signals and harmonics.

The mains only model 257/01 is small and lightweight and is ideal for bench use. Model 257/03 operates from mains or battery and is ideal for field or bench use. Model 257/05 is a mains only unit with GPIB option so can be part of an automatic test system.

Key Features include:

Frequency range 1.5 MHz to 2 GHz
Useful indications to 4 GHz
LED indication of lock, level set and function
Analogue display
Incorporates three bandpass filters, a psophometric filter, and a deemphasis network
Small, lightweight unit ideal for field use if battery version ordered
GPIB version for systems use
