A family of LAN-controlled transient recorders includes several high-speed modules that offer sampling speeds of 240 MS/s or 120 MS/s at 14-bit or 16-bit vertical resolution. The new compact TPCX-24014 and TPCX-12014 series Elsys Instruments combine measurement precision featuring vertical and offset accuracy specified at ±0.1% of full scale (typically ±0.07% after auto or induced calibration) with greatly increased sampling speeds.

Housed in a single-width PCI slot, the new transient recorders feature analog bandwidth at Nyquist frequency of 120 MHz for 240 M/sec versions and 60 MHz for 120 M/sec versions. They are suitable for a diverse range of power measurement applications including inverters, frequency converters, engine control and medical device testing. The new modules feature four single-ended channels that can be switched into two true, fully differential channels. Four differential channel recorders are obtained by mechanically and electrically integrating a pair of two-channel differential units.

The new data acquisition units offer many features such as a large input voltage range of up to 100V and an offset range of up to FSR on all sensitivity settings, 50?Ohm?and 1 Mega Ohm inputs, advanced trigger capabilities with external trigger inputs, programmable anti-aliasing filters, ICP current supply for piezoelectric sensors and digital input markers. Each input channel can be individually triggered, a feature unique to Elsys recorders. For example, four full trigger circuits are available on a four-channel recorder to obtain logic triggering such as "AND" and "OR." However, synchronization can be established as well with many associated channels. Advanced trigger modes include slew rate, pulse width, pulse pause, period, missing event, window in, window out as well as the usual edge pos/neg triggering, with trigger hysteresis values set by the user. Pricing starts at $12,400 for a 4-channel TPCX-24014 and at $11,450 for a 4-channel TPCX-12014. Delivery is six weeks ARO.
