The power meter's sensor head is equipped with a WR10 waveguide connector, so
depending on the frequency converter model a suitable WRxx to WR10 waveguide
taper is required. For details concerning its usage, see the respective PMx manual that
is available from the VDI Erickson power meter product pages (
index.php/en/products/power-meters-erickson
).
Control connection
The control units of the PMx power meters are connected to the R&S
ZNA via USB.
The PM5 control unit is equipped with a USB interface, for the PM4 an additional USB-
to-RS232 adapter is required. The PM5 can be auto-configured, the PM4 has to be
configured manually.
The required USB-to-RS232 adapter is not delivered with the PM4. Presumably, an
adapter-specific driver must be installed on the R&S
ZNA.
After installing the required drivers and connecting the PM4 to the R&S
ZNA, you can
find a new virtual COM port in the "Ports (COM & LPT)" section of your Windows
"Device Manager":
In the above screenshot, a converter cable with prolific chipset was used.
If you are in doubt about the related COM port, disconnect the PM4 and see which port
will disappear and appear after reconnecting.
