Teradyne 1890 ATE Test Equipment

The Teradyne 1890 test system provides a wide variety of board testing capabilities on digital, analog and hybrid circuit boards.

Features:
100VAC to 250VAC, 50/60Hz isolation transformer allows the tester to be moved anywhere with just changing the jumpers 32 pins per Drive/Receiver board

Analog Test:
Programmable 3, 4, 6 wire measurement accuracy
Complete coverage of R, L, C, diode, transistor, op amp, A/D, D/A and more
Programmable voltage and current stimulus and measurement
Quadrature measurement for low value capacitors and parallel RC networks
Mix-mode testing

Vector Features:
Vector Stimulus allows specifying drive high, drive low, or high impedance state for each pin and for each clock cycle.
Vector Measurement allows specifying except high, expect low, or ignore for each pin and for each cycle.
Measurement enables timing
Vector enable specifies each pin at each clock cycle independently Global Ignore specifies that all

Measurement types:
Signature Analysis (CRC) up
to 2 MHz, HICHECK identifies stuck high pins
Transition Counting (Count) up to 2 MHz
One COUNT or HIGH measurement per bust
Count and HIGH always fun in separate burst

Measurement enables timing:
Specified per measurement pin
All pins in a burst have same enable timing
Programmed in reference to Gray code
Frequencies
Pattern Depth: 32767 Max

Device Size Constraints:
Disables: 128 nodes Max
Device pins in test 128 Max
Guards per Test: 20 Max

Gary Code Features:
Up to 14 Gary code frequencies (F1 through F14) and their complements (F1* through F14*), preset high (PH), preset low (PL), preset pulse (PP), logic high (LH), and low logic (LL) can be applied to the device-under-test in any combination. Connect and disconnect features also provide synchronous three-state function.
