Introduction This document is a supplement to the operating manual of the Cobalt Series Vector Network Analyzers. This instruction sheet describes the general procedure for connecting frequency extension modules of any manufacturer. The Cobalt Series includes analyzers with loops on the configurable front panel enabling direct connection of frequency extension modules. - Page 5 Figure 1.2 Vector Network Analyzer. Connection of the TM0082 Module. The frequency extender modules are connected to the analyzer via a booster module set, the purpose of which is to ensure the mechanical mating of the device connectors and to set an acceptable power level of RF, LO and IF signals in the path.
- Page 6 Maintenance and operation of the analyzer should be performed by qualified personnel with basic experience in operating of microwave circuits. The manufacturer is not responsible for any consequences resulting from misuse of the ana- lyzer, including violation of safety rules or other necessary precautions.

Page 7: Safety Instructions
1 Safety Instructions Additional safety instructions can be found in the operating manuals of the analyzer and the frequency extenders to be used. Devices such as analyzer, booster, power supply, and frequency extender (refer to figure 1.2) must be grounded using their power cables. It is recommended to connect terminal on the device with the ground bus bar. -
Page 8: General Overview
2 General Overview 2.1 Description Analyzers in combination with the devices illustrated in figure 1.2 form a unified measurement system of complex transmission and reflection coefficients (elements of the scattering matrix) of N-port networks with extending the operating frequency range upper limit. This is the mil- limeter wave frequency extension system. -

Page 21: Connection Procedure
4 Connection procedure CONNECTION: The analyzer and the TM0082 module should both be OFF while performing any connection of cables, adapters or external amplifiers. The maximum input power of the RF signal or the maximum DC peak voltage as indicated on the devices’ housing should not be exceeded, doing so may damage them. - Page 22 Follow ESD and safety precautions while operating the devices. Remove the front handles of both devices. Screw the locking bars into place. When the analyzer is powered OFF, connect the loops to the configurable front panel, if they were disconnected before. Consistently connect the analyzer to the PC using the USB cable, and then to AC power.
- Page 23 Main Menu > System > Misc Setup > Frequency Extender > Custom Make sure that after connecting the instrument to the software, frequency sweep is performing over operating frequency range of the analyzer, and there are no errors indicated. Select the measurement mode with the external modules.
