Also, this device may be called: H148 X-1-48, 1 X 48, x1-48, X-148, X 148, X1 48, x148, x-1-48, x 1 48, x-148, x 148 , x1 48
H1-48 instruments for the study of amplitude-frequency characteristics of the frequency response possible to observe in broadband and narrowband devices, as well as two-frequency tags with different amplitudes on the CRT screen.
It consists of two units: the meter H1-48 and selective converter.
Frequency range - from 0.1 MHz to 150 MHz (0.1 MHz - 1.5 MHz, 1 MHz - 15 MHz, 10 MHz - 150 MHz).
- Maximum - the entire sub-band;
- Minimum - ≤2 kHz (0.1 MHz - 1.5 MHz); ≤20 kHz (1 MHz - 15 MHz); ≤200 kHz (10 MHz - 150 MHz).
The error in determining frequency - ± (3 · 10-4ƒ + 0,05Δƒ) Hz.
Output voltage sweep - not less than 0.5 (at 50 ohms).
Uneven own AFC maximum swing band on a linear scale - no more than ± 0,4 dB (30 MHz); ± 0,5 dB (above 30 MHz).
Limits output voltage adjustment sweep - 0 dB - 70 dB (with a resolution of over 1 and 10 dB).
Uneven output voltage H1-48 - ± 1 dB.
The dynamic range of playback frequency response in a linear scale - 14 dB.
The duration of the periods of automatic swing - 0.08; 1; 10; 40 (manual start).
The sensitivity of the channel vertical deflection - not less than 3 mm / mV.
Power consumption - 100 V · A.
- AFR meter H1-48 - 490h482h175 mm;
- Converter - 490h475h135 mm.
- Frequency response of the meter - 25 kg;
- Converter - 15 kg.
Selective expansion of the transducer provides measurement limits relative amplitudes.
