4.3 System Configuration with VDI Modules
The VectorStar Millimeter-Wave system provides control of VDI modules for frequency extension coverage up to 750 GHz and beyond. MS4640A
series VectorStar VNA may be configured for mm-Wave operation by adding the appropriate control option and test set. System requirements
include:
• MS4642A, MS4644A, MS4645A, or MS4647A Model VectorStar VNA
• MS4640A Option 007, Receiver Offset
• MS4640A Option 080, 081, 082, or 083
• SM6537 Interface Cable
• 3739B Test Set
Each VDI module is equipped with a dedicated external power supply and DC cable. Connection between VectorStar and the VDI mm-Wave
module is provided with the supplied interface cable.
4.4 VDI Module Specifications
Dynamic range and stability specifications are valid for any MS4640A VectorStar VNA with appropriate options. Directivity specifications are valid
when using appropriate VDI calibration kits.

VDI Millimeter-Wave Extenders Summary Specifications
a
a. Specifications. These results assume a through measurement with two TxRx Heads. The specifications quoted here are "expected" and subject
to change. Stability is for 1 hour after a 1 hour warm-up, in a stable environment with ideal cables. The dynamic range (RBW 10 Hz) is
measured by first connecting two TxRx heads together and normalizing the un-calibrated S
21
. The heads are then disconnected and
terminated with a waveguide load. The RMS of the measured S
21
parameter is the system dynamic range.
