VM1001 Two-Channel Absorbed Power Meter

 

  • Message based interface

  • Interrupt functions

  • Serial number indentifier

  • Automatic calibration

  • Automatic and manual measurement range switching

DESCRIPTION

 

The Two-Channel Absorbed Power Meter with eight power sensors measures average power of sine-wave and pulse-modulated microwave signals in two independent channels with measurement accuracy 4–6 % in the operating frequency range

(DC – 37.5 GHz) and in the dynamic power range (from 0.1 mW to 100 W).

The Instrument is manufactured in C-size 2-slot cabinet with VXIbus interface.

The Instrument has an automatic and manual switching of measurement ranges, automatic zeroing and calibration. Provides limit control in accordance with low and

high (set) measurement power levels.

The Power Meter stores the correction coefficients for certification of 16 sensors
(10 points for each sensor) and takes them into account in the process of measurements, when there is no data for any sensor in the Instrument memory.

 

SPECIFICATIONS

 

Channel switching frequency (when operated in an automatic measurement system composition): 1 Hz

8 sensors allow to make measurement in:

0–37.5 GHz frequency range

10–7–100 W (–40…+50 dBm) power range

Measurement accuracy: ±4–6 %

Zero drift: 0.4 mW/min at the most sensitive range
