Measuring AFR & nbsp; H1-54 & nbsp;. Is designed to study the frequency response of radio digital readout of measured values ​​and playing the AFC on the CRT screen

The device H1-54 used in various electronics fields in the laboratory and shop floor, as well as in repair and calibration bodies.

Integrated microprocessor provides the automation of the process measurements and processing the results of measurements, automatic calibration and correction of the own frequency overshoot, automatic installation of the frequency band, soft detuning of noise during operation of the signal at low level, input and storing in the memory of the reference frequency response and conduct in relation to its comparative measurements, there are a number of service functions.

The interactive mode of operation of the digital reference H1-54 make the device convenient and easy to use.

& nbsp ;

Main technical characteristics of the device H1-54:

frequency range: 0.1-150 MHz

The number of sub-bands: 2 (0,1-5,7; . 5,6-150 MHz)

band rocking 1.5 kHz - all subband

Measurement limits relative amplitude frequency response, at least in dB; & nbsp;
<. . br /> 120 (if heterodyne conversion), & nbsp;

80 (at the amplitude detection)

band parasitic FM: & nbsp;

450 Hz (I subband), & nbsp;

3 kHz (II subband)

The measurement error of the relative amplitudes of the frequency response in dB:

& plusmn; (0,05 Ah 0. 4) (0-20 dB); & nbsp;

& plusmn; 1,5 (20-70 dB)

Dynamic playback frequency response range: 70 dB ..

The level of spurious oscillations at the output sweep not more than -25 dB

Uneven own frequency response of not more than & plusmn; 0,4 dB

consumption:.. 320 B * a <. / p>
