The Model 8850 Attenuation Measurement System combines the outstanding accuracy, performance, high sensitivity, and reliability of our Model VM-7 Attenuator and Signal Calibrator with our Model 8852, 0.01 to 18 GHz Frequency Converter.
When combined with a suitable generator, the Model 8850 provides the user with an attenuation calibration system of high accuracy, repeatability and speed. Some other features of this system include:
Advanced Techniques
Advanced digital detection and processing techniques of the VM-7 means that measurements are available instantaneously, no matter what the dynamic range or resolution.
Single Band Operation
The system can be converted to a 0.01 to 18 GHz single port converter. This is accomplished by using the measurement accessory kit (P/N 187- 4001) that is supplied as part of the system. The measurement accessory kit includes low SWR masking attenuators and a power divider to provide a measurement system as shown in Figure 1.
Dual Band Operation
The RF input frequency range is divided into two bands, 0.01 to 2 GHz, and 2 GHz to 18 GHz. This allows the user direct access to the RF port of either the LOW band or HIGH band mixer to make full use of the VM-7 dynamic range.
IEEE-488 Bus Programmable
Remote programmability over the IEEE-488 bus using an external controller or controlling the system using only the VM-7.
Auxiliary Output
An auxiliary output of 2 to 18 GHz synthesized continuous wave signal in 2 kHz steps at +7 dBm is available, which can be used as an RF signal source for other applications.
Versatile and User Friendly
This measurement system will test all types of attenuators such as fixed, manual, motorized, programmable and other coaxial components. Coaxial components can be quickly and accurately tested using the efficient, user-friendly 8850-SureCAL software |
