Transient Recorders Merge High-speed with High-precision and Long Memories

Tue, 11/02/2010 - 3:57pm
Elsys Instruments has expanded its family of LAN-controlled transient recorders to include several high speed modules that offer sampling speeds of 240 MS/sec or 120 MS/sec at 14-bit or 16-bit vertical resolution. The new compact TPCX-24014 and TPCX-12014 series combine Elsys' unique measurement precision featuring vertical and offset accuracy specified at ±0.1% of full scale (typically ±0.07% after auto- or induced calibration) with exceptionally increased sampling speeds.

  Housed in a single-width PCI slot, the 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 ideal for a diverse range of power measurement applications including inverters, frequency converters, engine control and medical device testing.

  Specialty applications include ballistics and explosive tests, acoustic emissions, ultrasonic testing, fluorescence and phosphorescence decay studies and particle accelerator control.

  The TPCX-24014 and TPCX-12014 series were designed for application flexibility. 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.

  Standard acquisition memory length on the new units is 32 Mpoints/channel with an optional 128 Mpoints/channel available for increased digital bandwidth so that signals may be sampled proportionally faster for the same event duration.

  The data acquisition units offer many sophisticated 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.

   The TPCX-24014 and TPCX-12014 provide unprecedented flexibility in configuring unique solutions for individual measurement needs. Several data acquisition modes are featured, including scope mode, similar to an oscilloscope, that enables the quick configuration of the acquisition parameters before working in a different mode or simply the ability to visualize and analyze single-shot events.
