3.1 SPECIFICATIONS
Input Characteristics
Level
VHF/UHF/ SAT from 20 to 130 dBµV (-90...20 dBm).
HF from 30 to 130 dBµV (-80...20 dBm).
Measurement unit
dB (for ratio measurements) - dBµV - dBmV - dBm into 75 Ω - V
(Volt) independently selectable for level and power measurements.
Attenuator
VHF/UHF/ SAT from 0 to 80 dB in 10 dB steps.
Manual or autoranging, switchable.
Attenuator Accuracy
VHF/UHF ± 1 dB - SAT ± 1.5 dB.
Frequency response
Within ± 2 dB between 45 and 2050 MHz, ± 2.5 dB between 2050 and
2150 MHz.
Reading
1. Numerical by means of OSD (On Screen Display) technique with
0.1 dB resolution.
2. Relative, on the screen against a 30 dB scale.
3. Aural; tone proportional to signal level.
Measurement
Switchable to peak or average value of the modulation and, reading in
true rms value for a CW sine wave.
Measurement
