Wavenode SWR meter
WN-2D: Multichannel SWR/Powermeter with USB connection
WN-2D Front View
The new WN-2D power meter measures and displays output power or SWR of up to four radios/antennas at the same time.
Up to four sensors for power/SWR can be connected to the device and can be installed at the point where they are required; sensors are available for 1.6 to 1300MHz and up to max. 8KW.
The measured data is displayed on a computer connected via USB. The required software (for Windows XP or newer, 32/64 bit) is included.
When operating standalone the data is shown on the internal LC display and 2 bargraphs at the same time. So a computer is not required, but of course would give a much better overview.
The WN-2D measures spectrum and envelope of the transmitted signal up to 20 kHz modulation bandwidth. Intermod, splatter or overmodulation can be seen immediately. The required fast sampling rate of the transmitted signal is achieved by using a fast RISC processor in the sensor.
Additionally the WN-2D offers four analog (0 to 10V) and four digital (TTL) inputs for many measurement tasks. A programmable solenoid output offers the possibility to emergency shut-down, for example in the case of high SWR.
The device is shipped including one HF 2kW sensor, CD-ROM, USB cable and power supply.
HF- and SHF-Sensor 2kW with RF-View.
This new sensor offers an additional output (BNC female). This output signal can be connected directly to an oscilloscope and allows to monitor the trnasmitted signal in realtime. This is very useful to monitor distortions etc.
Cable length of sensors
The supplied cable on the sensors is approx. 1m long. This cable can be extended nearly without limit, there is not HF on this cable. Still you should use a shielded cable (2 wires).
