Resonance Dip Meter
NRM-2
-
National RF’s Resonance Dip Meter is a test instrument used to determine the resonant frequency of a tuned circuit or resonant network, such as an antenna system. In addition, the unit may function as an RF detector, or a secondary frequency source. The instrument is analogous to the older vacuum tube “grid dip meter,” once popular in every electronic laboratory or radio station. Unique to this updated version is a buffered output that may drive a digital frequency counter for exact measurement of resonant frequency, or connected to an oscilloscope to be used as an RF detector and waveform/modulation monitor.

NI-9361, 32-Bit, 8-Channel C Series Counter Input Module
783407-02
Counter Input Module
32-Bit, 8-Channel C Series Counter Input Module - The NI‑9361 is a differential or single-ended input module. With this module, you can expand beyond the four counters in CompactDAQ to reach up to 64 counters per 8‑slot chassis. You can configure each channel to read a single pulse train or combine them to read up to four incremental encoders. You can also directly connect sensors with open-collector or push-pull outputs by using an internal switchable 1 kΩ pull‑up resistor. The NI‑9361 counters can perform encoder position and velocity measurements. You can synchronize the counters with other analog, digital, and counter measurements in your chassis.
