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)... -126 dBm
Level setting intrinsic error < 3 dB
Auxiliary error < 0.1 µV

QAM setting error < 10%
Modulation signal frequency (step 1 Hz) 20 Hz ... 20 kHz
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 %
FM deviation 0.1 ... 20 kHz
Error < (0.1+0.1·D) kHz
Modulation rate 0...100%
Error < 10%
LF 10 Hz ... 100 kHz
HF 1.6... 470 MHz
Reference generator instability < 10-6*
Frequency band 20 Hz ... 10 kHz
Limits 1... 50 %
Error < (5+5·Kmst)%
Range 0.02 ... 20 V
Frequency band 20 Hz ... 20 kHz
Error < (0.02+0.03·U) V
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
