Features:
- Meets Requirements for Joint Services Military ATE Programs
- Perform Precision Timing Measurements with Unsurpassed Resolution
- Programmable Load
The EADS 2681 Frequency/Time Interval Counter + Load is a higher-performance, 2-channel, universal 200 MHz timer/counter. The 2681 includes a high-performance
universal counter offering five automatic measurement functions: Frequency, Period, Time Interval, Time Interval Delay, and Totalize.
The 2681 counter offers 200 MHz
frequency measurements with up to 9 digits
of resolution per second. In Time Interval
mode, the resolution is 1 ns in single shot
and 100 ps in average mode.
By using Time Error Correction (TEC)
in combination with traditional recipromatic techniques, measurement time
is minimized without any performance
compromise.
Programmable measurement Timeout
enables system performance to be optimized where input signals are missing.
The trigger level is programmable from
-5.1 V to +5.1 V (-51 V to +51 V in x10
mode) with a resolution of 2.5 mV (25 mV
in x10 mode).
The 2681 counter offers independent
50 kHz low pass filters on each channel
to allow measurements in noisy
environments.
The sensitivity of the counter can be
reduced to optimize the front end for low-level or low slew rate signals with noise.
This feature is also very important for
system applications, where noisy signals
are encountered. Four standard sensitivity
settings are provided.
Nine different modes are provided with the
ability to select the arming source between
the external arming input and the VXI TTL
trigger lines.
The 2681 counter includes a five-watt
programmable resistive load. The load is
programmable from 1 Ω to 100 k Ω with
0.1 Ω resolution and provides a stable
resistance value under all operating
conditions. The load has built-in overcurrent, over-voltage, over-power, and
over-temperature protection, which opens
the load terminals under any fault condition
making it difficult to damage the 2461-LWC2 load.
The 2681 load uses software calibration
factors stored in non-volatile memory to
maintain its accuracy. Softcal is automated
and can be performed by connecting the
load terminals to a DMM, but it can also be
performed manually
The EADS 2681 Frequency/Time Interval Counter + Load may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
