*WM164 (WR0.65) performance is specified for a TxRx-Rx configuration using external synthesizers. Performance of a TxRx-TxRx configuration is estimated to have a ~15 dB degradation of dynamic range and may additionally require the use of a mmWave controller. 
Test Port Input Powers exceeding the peak Test Port Power of the TxRx or TxRef module will compress the module.


General Notes: 

Extension modules are compatible with all modern VNAs. Please consult with VDI to discuss VNA and module configurations that will yield the best performance for your application.

 
Technical Notes:

1. Test Port Power is typical, reduced power is possible at band edges. Range is measured on PNA/PNAX front-panel with internal synthesizers, using a controller can reduce DR by ~5-10 dB.

2. Stability is specified for 1 hour after system warm-up, in stable environment with ideal cables.

3. Specifications assume a through measurement with two TxRx heads.

4. Specifications are measured on a Keysight PNA/PNAX with front panel connection at 25°C typical.

5. The dynamic range (RBW 10 Hz) is measured by first connecting two TxRx heads together and normalizing the un-calibrated S21 & S12. The heads are then disconnected and terminated with a waveguide short. The rms of the measured S21 & S12 give the system dynamic range.

6. Typical Module Dimensions exclude testport (2" standard testport for all modules except WM250 (WR1.0), where a 1" testport is used)

Where noted, Extended Frequency Coverage applies; module performance within the standard band conforms to standard specifications while performance in the extended regions can be degraded as follows:

-The minimum and typical dynamic range is degraded by 10dB or less, compared to the specification for the standard band. 

-The test port power typical across the extended band is degraded by 5 dB or less compared to the specification for the standard band.
