Technical characteristics

1. HF generator

Baseband90... 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 mode0.1 ... 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 deviation0.1 ... 20 kHz

Error< (0.1+0.1*D) kHz

Modulation rate0...100%

Error< 10%

4. Frequency meter

LF10 Hz ... 100 kHz

HF40 MHz... 240 MHz (...1000 MHz)

Reference generator instability< 10-6*

5. Distortion meter

Frequency band20 Hz ... 10 kHz

Limits1... 50 %

Error< (5+5*Kmst)%


6. DC voltmeter

Range0 ... 30 V

Error< (2+2*(Uk/Umst))%

7. AC voltmeter

Range0.02 ... 20 V

Frequency band20 Hz ... 20 kHz

Error< (0.02+0.03*U) V

8. Power meter

Level0,5 ... 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
