The Marvin Test MV-GTX2230 PXI universal time interval counter offers many of the measurement and timing functions of high-end stand-alone frequency counters, including accumulate, auto ratio, frequency, fast frequency, period, ratio, single period, test clock, time interval, time interval delay, totalize, totalize gated, totalize gated once, & pulse width. The MV-GTX2230 covers frequencies up to 2.0 GHz. The card is also available in PCI format (GC2230).
The MV-GTX2230 counter has two signal input channels via BNC connectors, an external timebase input, arm input, and a gate signal output. The separate input signals can be used for arming and gating the circuitry, and controlling the timing of the analysis (start / stop duration) for maximum measurement flexibilty.
The MV-GTX2230 counter uses an on-board microprocessor with embedded firmware to off-load processing tasks from the main CPU. The counters use high-density, low-power field programmable gate arrays (FPGA) to perform complex logic tasks. Reciprocal counting techniques are used to achieve high resolution measurements on lower frequency signals without sacrificing measurement time. These techniques provide a fixed number of digits of resolution for all frequencies rather than a fixed resolution in Hz for the same gate time.
The Marvin Test MV-GTX2230 can measure frequencies to 0.1 parts per million (seven digits) in just 1 ms and resolve each time measurement to 100 ps. This ability to precisely resolve frequency and time allows for increased accuracy as well as reduced measurement time. When combined with 2,300 measurements / second, one of the fastest rates available, more data can be acquired in a single second than a typical GPIB counter can acquire in one minute.
Additionally, the counter includes an on-board 10 MHz TCXO timebase for internal frequency reference. As an option, a high precision 10 MHz OCXO is available for the MV-GTX2230 model. An external 10 MHz input is also availble for use with external timebases.
