Tenma 72-455 - Features; Specifications; Frequency and Accuracy; Sine Wave Characteristics

FEATURES
* All solid state circuitry insures extreme high stability,
minimum warm-up time and less power consumption.
* High reliability with adoption of direct coupled circuits
throughout the entire stage.
* Compact styling with vertical type panel for easy
operation.
* Frequency dial scale calibrated with single-scale gradua-
tions
for frequency range of 10Hz to 1 MHz selectable
in
5' ranges.
* High output design; more than. 7V rms at no load and
more than
3.5V rms at 600n (Sine Wave). Output
level is fully adjustable with a 10dB-step, 6 range
attenuator and a level adjuster.
* Low output impedance of 600n. The attenuator pro-
vides accuracy
of ±1.0dB at 600n load.
* Sine and square waves easily available.
* Synchronizing
input terminal.
