   Data format

The EXTREME1 records 2.23 seconds of an analog signal within a range of 0 Hz through 230,000 Hz, and will convert and store this signal as 16-bit by 1-Meg data words.  Any signal within zero and five Volts, and  within this frequency range, will be free of NYQUIST imaging.  The EXTREME1 utilizes 32-times oversampling and digital filters, as well as analog filters, to provide NYQUIST Image-free recordings up to 230 KHz.  Bridge excitation (+5v reg. @ 30 mA) is provided.

Signal bandwidth: 0 Hz through 230 KHz
Recording length: 2.23 seconds, with programmable pretrigger length
Bridge instrumentation amp configuration
256-step programmable digital gain and offset in 65535 bytes-per-step (16 steps)
Onboard sensor supply: 5 V @ 30 mA
Optional user-selected offset and gain resistors
Dual digital FIR filters (128-tap and 83-tap)
"Brute force" 250 KHz low-pass
Automatic, on-board 0.223 second shunt test (0.06 seconds no shunt, 0.1 sec. user-selected shunt, 0.063 s no shunt)
Current consumption:  <30 mA @ 9V (standby); <120 mA @ 9 V (arm/record)
Battery voltage (0-25VDC @ 1.25 V/Div) and signal level display (0-2.5VDC @ 0.125 V/Div)
Auto nap:  display will shut off approx.13 seconds after last button press
Approximately 3.0 in. x 2.5 in. x 2.0 in., including connectors (less control panel)
