Technical characteristics 1. HF generator Baseband 90... 210 MHz Allowed additional bands - by agreement with the Customer (frequency step 1 kHz) 100kHz...470(527) MHz Carrier setting error < 10-6* Deviation in FM mode 0.1 ...

20 kHz(step 10 Hz) Deviation setting error < 10% Output signal level (step 1 dBm) -60 (-80)... -120 dBm Level setting intrinsic error < 3 dB Auxiliary error < 0,1 µV Amplitude modulation(option) 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 < 0.2 Hz Output signal level (step 10 mV) 0 ... 2 V Setting error < (0.01+0.03*U)V Distortion factor < 0.3 %

3. Modulation meter FM deviation 0.1 ... 20 kHz Error < (0.1+0.1*D) kHz Modulation rate 0...100% Error < 10%

4. Frequency meter LF 10 Hz ... 100 kHz HF 40 MHz... 240 MHz (...1000 MHz) Reference generator instability < 10-6*

5. Distortion meter Frequency band 20 Hz ... 10 kHz Limits 1... 50 % Error < (5+5*Kmst)%

6. DC voltmeter Range 0 ... 30 V Error < (2+2*(Uk/Umst))%

7. AC voltmeter Range 0.02 ... 20 V Frequency band 20 Hz ... 20 kHz Error < (0.02+0.03*U) V

8. Power meter Level 0,5 ...

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)] %

* If necessary, a reference generator with stability of up to 5*10-7 can be added. 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. Carrying case Dimensions: 270 × 160 × 270 mm
