Read all instructions and information in this product manual before connecting a module to its power supply or a signal
generator. Operational procedures must be followed for proper function. If you have questions, contact VDI before
supplying power to or otherwise operating any VDI module.
VDI assumes the customer is familiar with microwave, millimeter wave and VDI products in general. The user and
customer are expected to understand all safety guidelines, health hazards and general advisories that may exist and
are associated with the use of this device. VDI is not responsible for any human hazards that may exist or may occur
while using this device.
RF Drive Limitations
Recommended RF input power specifications are noted on the label on the top of every VDI module. See examples on
Page 8; these values provide optimal performance. Irreversible damage can result if input power exceeds stated
damage threshold.
Virginia Diodes, Inc. (VDI) accepts no liability for damage or injury resulting from or caused by:
•
Improper use, disassembly or use for purposes other than those for which the module was designed;
•
Use outside common safety, health or general advisories pertaining to microwave, millimeter wave and VDI products;
•
Repairs carried out by persons other than VDI or its assigned agents;
•
Tampering with or altering power cords or other cabling.
Waveguide Inspection / Test Port Care
•
Inspect waveguide flanges prior to making connections.
•
Extension module waveguide screws should be torqued in the range 20-50 cNm, greater torque can damage the
interface.
•
Making a connection with metal debris between the waveguide flanges can damage the waveguide interface and prevent
repeatable connections.
•
If debris is present, clean the flange with pre-dampened TexWipe wipes or swabs (e.g. Part Number TX1065).
•
If these are not available, TexWipe cloths lightly dampened with ethanol may be used (e.g. Part Number TX604).
•
Replace dust caps when the system is idle.
RF Cable Care
•
Use a torque of 90 cNm when making coaxial connections. Avoid sharp bends in cables.
General Operating Practices and Recommendations
•
VDI SGX Modules are intended to be used in typical laboratory conditions.
•
Use of any attachments and accessories not authorized by VDI or that do not meet VDI’s specifications may void a
module’s limited warranty and could pose a hazard to the operator, or cause lasting damage to the device.
•
DC bias cables provided by VDI must be used. Alternative and replacement cables cannot be used unless the DC cables
are adequately rated, properly grounded and authorized for use by VDI.
•
Each VDI module is intended for use only with its AC/DC converter as supplied by VDI. Use of other power supplies or
converters could damage the device or injure the operator.
•
Disassembling a module can cause lasting damage to components and pose a hazard to the operator.
•
Applying liquids (other than the TexWipe wipes / cloths used for cleaning) can cause lasting damage to the module.
•
Check with VDI before any measurement connection is attempted beyond those described in this manual or if it may
exceed commonly accepted standards of practice.
