Wayne Kerr 257-05 Specs:

Wayne Kerr 257-05. Automated Modulation Meter (2 GHz) with GPIB

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.


* 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
