Digital/Analog Frequency Response Analyzer
8800 Series
-
The analyzer utilizes a digital “Sync” signal to provide synchronization between analog and digital hardware. The Model 8800 performs simultaneous analysis on both analog input channels and digital target processor, reliably capturing all data. Versatile by design, the Model 8800 digital interface can be disabled, via software, to use the analyzer in a standard 2-channel, analog-only configuration.

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.

Radio Frequency Cable Tester
RFCT
-
Textron Systems’ Radio Frequency Cable Tester (RFCT) allows for on-site testing and maintenance for radio frequency (RF) transmission paths within a platform. Using preconfigured databases of sweep parameters and pass/fail criteria, the RFCT quickly determines the status of installed RF cables. The RFCT checks each cable’s performance characteristics to include voltage standing wave ratio (VSWR), insertion loss (IL), phase and phase matching. If a cable fails a test, the RFCT automatically determines the distance-to-fault (DTF). With its intuitive touchscreen-based user interface and lightweight, ruggedized packaging, the RFCT is the gold standard for operational-level RF cable testing.

High Frequency Current Transformer
HFCT Ø 140mm
-
Techimp Clamp High Frequency Current Transformer model 140 is an inductive sensor for partial discharge measurements. It is suitable for online /off line PD tests on : large diameter cables ; grounding rod bar ; etc. A TNC termination is available to connect the Clamp HFCT 140 to the TechImp PD analyzer : PDCheck , PDBase etc. The arrow indicates the requested input current (Iin) direction to get coherent output voltage (Vout) polarity respect to ground. When the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase of the input current (Iin).

UV & Visible Frequency Mixing Module
SolsTiS EMM
-
The SolsTiS External Mixing Module (SolsTiS EMM) provides fully automated tuning in the visible (480-670 nm) and IR (1.1-4.5 µm) with further extensions options into the UV (300-350 nm). It delivers high stability sum and difference frequency mixing of SolsTiS wavelengths with other single frequency sources, primarily via high efficiency single pass mixing in PPLN. This all-solid state solution for wavelength coverage supersedes dye lasers, removing the hazards and instabilities associated with this toxic gain material. SolsTiS EMM delivers unparalleled performance and reliability, enabling you to automatically tune and scan over a broad wavelength range.
