Measuring AFR & nbsp; H1-55 & nbsp;. Is designed to study the frequency response radioustroysta with digital readout of measured values ​​and the AFC playing on the CRT screen

H1-55 is used in various fields of electronics . in laboratory and plant conditions, as well as repair and calibration bodies

provides a built-in microprocessor; automation of the measuring process and processing of measurement results; Automatic calibration and correction unevenness own frequency response: the automatic installation of the frequency band; soft detuning from noise when operating at low signal levels; input and storage in memory of the reference frequency response and conduct comparative measurements with respect to it:. there are a number of service functions

The interactive mode of operation of the digital reference H1-55 make the device convenient and easy to use & nbsp;

Main technical characteristics of the device H1-55:

frequency range: 1-1400 MHz

The number of subbands: 3 (1-11; 10,8-132; 128-1400 MHz)

band oscillation: 0.1 - whole subband

error.. measuring the relative amplitude (at KCBH less or equal to 3), not more than: & nbsp;

& plusmn; (0,4 + 0,05 x A) dB (0-20) dB; & nbsp;

& plusmn; 1.5 dB (20-70) dB

limits relative amplitude measurements, however, dB;. & nbsp;

130 (if heterodyne conversion), & nbsp;

90 (at the amplitude detection)

band parasitic FM sweep output signal, no more kHz: & nbsp;

5 (I subband); & nbsp;.

20 (II subband); & nbsp;

200 (III on . Ddiapazon)

Output VSWR sweep no more than 1,5

Power consumption:. 380 V * A .
