4 Dismounting Frequency Converters
The frequency converters may be dismounted from the external test sets and used sep-
arately. They can be used in combination with any network analyzer R&S ZVA or R&S
ZVT with an upper frequency limit of 20 GHz or higher (R&S ZVT 20, R&S ZVA 24, R&S
ZVA 40 ...).
The frequency converters provide:
●
A frequency range between 50 GHz and 75 GHz
●
Direct connection of DUTs with waveguide flanges
●
System error correction using waveguide calibration kits (e.g. R&S ZV-WR15)
For detailed information about measurements with external frequency converters refer
to the Quick Start Guide R&S ZVA-Z75, Z110 ..., stock no. 1307.7039.62, which is posted
on the R&S internet, and to your network analyzer's help system.
Dismounting the converter
To detach the frequency converter from the diplexer:
1. Unscrew the semi-rigid RF cable between the RF HIGH OUT connector on the top
side of the diplexer and the RF IN connector on the rear panel of the converter.
2. Turn the external test set by 90 deg so that the diplexer connectors point in upward
direction.
3. Open the corrugated union screw of the power supply cable between the converter
the diplexer manually, leaving the cable attached to the diplexer.
4. Open two screws at the U-shaped metal clamp, leaving the clamp attached to either
the converter or the diplexer.
5. Put the external test set back on its feet.
6. Use the hexball driver supplied with the R&S ZVA80 to open all screws at the wave-
guide flange, leaving the flange attached to the converter.
7. Carefully detach the two devices in horizontal direction.
Risk of damaging waveguide flanges
The waveguide flanges of the dismounted converter and of the test port adapters must
be protected against mechanical damage. Furthermore the waveguides must be shielded
from dust.
Protect the waveguide flange of the dismounted converter by leaving a test port adapter
connected. When the converter is not in use attach one of the included protective caps
to the adapter. Avoid scratching the contact surfaces of the waveguide flanges.
