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. |
