Technical characteristics
1. HF generator
| Band | 1.6... 470 MHz |
| Carrier setting error | ± 3·10-4 % |
| Deviation in FM mode | 0.1 ... 20 kHz (step 10 Hz) |
| Deviation setting error | < 10% |
| Output signal level (step 1 dBm) | -27... -126 dBm |
| Level setting intrinsic error | ± 4 dB |
| Amplitude modulation | 0…100% |
| QAM setting error | < 10% |
| Modulation signal frequency (step 1 Hz) | 20 Hz ... 20 kHz |
2. LF generator
| Frequency band (step1 Hz) | 20 Hz ... 20 kHz |
| Frequency instability | ± 1Hz |
| Output signal level (step 1 mV) | 1 mV ... 2 V |
| Setting error | ± (0.02+0.05·U)V |
| Distortion factor | < 1 % |
| FM deviation | 0.1 ... 20 kHz |
| Error | ± 10 % |
| Modulation rate | 0...100% |
| Error | < 10% |
| LF | 10 Hz ... 100 kHz |
| HF | 1.6... 470 MHz |
| Frequency band | 200 Hz ... 10 kHz |
| Limits | 1... 50 % |
| Error | ± 6 % |
6. AC voltmeter
| Range | 0.02 ... 15 V |
| Frequency band | 20 Hz ... 20 kHz |
| Error | ± 6 % |
7. Power meter
| Level | 0,2 ... 20 W (up to 50 W - w/ external attenuator FAD-2, up to 100 W - w/ FAD-3, by agreement with the Customer) Note that when using the FAD type fix attenuators or analogs for measuring parameters of radio transmitter with the output power above 20 W, the power value measured by the device must be multiplied by the attenuation (fading) ratio of the attenuator by the formula Ratt=10 to the power of Ratt, dB/10) |
| Error | < [10+(Pk/Pmst)] % |
NVRAM can be used for storage of the test results.
The device can be supplied with a power source which provides not less than 4 hours offline
Also a solar cell battery can be used as a power supply.
