NI-9253, 50 kS/s/ch, ±20 mA, 24-Bit, 8-Channel C Series Current Input Module
785989-02
50 kS/s/ch, ±20 mA, 24-Bit, 8-Channel C Series Current Input Module - The NI-9253 is an 8-channel analog input module for ComapctDAQ and CompactRIO systems. Each channel provides a ±20 mA input range and 24 bits of resolution at a 50 kS/s sample rate. The NI-9253 has several diagnostic features to ensure your system is operating nominally at all times with open channel detection, power supply detection, and configurable thresholds. The NI-9253 has eight LEDs to indicate the status of each channel and the power supply so that a user in the field can easily validate that the system is operating normally. The NI-9253 also features a number of programmable hardware filters. By choosing the specific Butterworth and comb filters for your application, you can significantly reduce the noise in your system.

Source of Signals
CRS+
The CRS+ is a stable and calibrated source of signals which cover the 9KHz - 30MHz frequency range. The fundamental signal is a 15KHz comb and each harmonic is output as a narrowband peak of known amplitude. This signal is output on either the L and N lines, referenced to ground. A switch provides on/off and line selection.

Comb Generators
Keysight comb generators provide excellent phase and amplitude flatness making them ideal for use in phase calibration applications. A customer selectable USB-controlled frequency divider which allows for broad range of input signal frequencies from 10 MHz to 67 GHz and small minimum tone spacing of 10 MHz, makes Keysight comb generators suitable for characterizing non-linear devices.

Vector And Scalar Mixer / Converter Measurements
S95083B
The Keysight S95083B measurement software includes the scalar mixer / converter plus phase (SMC+Phase) measurement class. It provides fully calibrated conversion gain / loss, relative phase, and absolute group delay measurements of mixers and converters without the need for reference or calibration mixers. Eliminating the calibration mixer requires a U9391C / F / G comb generator and an external DC power supply. A vector mixer characterization (VMC) is also included for measuring group delay of frequency-converting devices. VMC can be used to characterize a user-supplied calibration mixer.

Uncured Powder Film Comb
155
This enables the application system to be set up and fine tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray.Place the comb into the powder and slide the comb along the surface. The measurement points (or teeth) are pointed and allow the powder to flow around them.

Emissions Reference Source
ERS
The ERS is a comb generator that radiates RF continuously every 2MHz over the range 30MHz - 1000MHz. Each 2MHz peak is precisely measured during the calibration process with the ERS orientated both vertically and horizontally. These measurements are correlated against a 3m OATS such that any fully implemented CISPR16 site, measuring at 3m and using height scanning, will read the same.
