2-18GHz Instantaneous Frequency Measurement Unit
DR073
-
Teledyne Defence & Space’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offers high speed frequency measurement across the full operating bandwidth.The IFM measures the frequency of RF signal present at its input and presents a result at its output as digital data. The RF input signal is conditioned by an RF amplifier that provides sufficient drive for the frequency resolving circuits. The raw video from the resolvers is digitised and processed into the required output format. There is additional timing and control circuitry which initiates the measurement process and provides handshake data to the host system processor.

HIGH FREQUENCY DC BIAS
6565 SERIES
-
The 6565 HF DC Bias Unit is intended to be used with a Wayne Kerr 6500 analyzer, either the 6500B Precision Impedance Analyzer or the 6500P HF LCR Meter. Its function is to provide a source of DC bias current through the Device Under Test (DUT) while the analyzer is making AC measurements. Each 6565 unit can provide up to 10 A of DC current, and up to six 6565 units can be connected in parallel to supply a maximum 60 A. A digital ammeter on the front panel allows the user to see the dc bias current value and an indicator LED shows when the bias current is enabled.
