ASL 1000 Instrument Cards

以下記錄ASL1000/3000的板子的縮寫及其簡單工能描述。

Each ASL 1000 test instrument is contained on a type B VME-sized card that plugs into the test head backplane (slots 1-21). Up to 21 test instrument cards can be mounted in the backplane. Many of the instrument cards have user-accessible test points located along one edge for debugging.

 

1. ACM: 「Alternating Current Multiplexer」 --- High-speed test site for testing digital clock devices.

2. ACS: 「Alternating Current Source」 --- Arbitrary waveform generator and alternating current meter.

3. ASB: 「Analog Switch Board」 --- 20-channel analog switch tester.

4. DCC: 「Data Converter Card」 --- Highly flexible card for testing ADCs, DACS, and other converters.

5. DDD:「Digital Driver and Detector」 --- 8-channel digital pattern generator for digital signal stimulation and readback.

6. DOAL:「Dual OpAmp Loop」 --- High-precision opamp and comparator resource for testing amplifiers in a closed-loop configuration.

7. DVI: 「Dual Voltage/Current Source」 --- Two-channel, medium-current V/I source; provides true four-quadrant force/ measure operation and rapid settling time.

8. HVS: 「High Voltage Source」 --- High-voltage, low-current floating source.

9. LZB: 「Link/Zener Blower」 --- Single quadrant V/I source optimized for the link and Zener blows.

10. MVS: 「Medium Voltage Source」 --- Medium-voltage, medium-current floating source.

11. MUX: 「Resource Multiplexer」 --- Relay card.

12. OFS: 「Octal Floating Source」 --- Medium-voltage, medium-current floating source.

13. OVI:「 Octal Voltage/Current」 --- Eight-channel, low-current V/I source that offers four-quadrant force/measure operation.

14. PMU: 「Precision Measurement Unit」 --- Extremely precise measuring unit that sources and measures up to 45 V and 1 A.

15. PRO: 「Prototyping」 --- Configurable card used to create custom circuitry for various DUT applications.

16. PVI: 「Pulsed V/I」 --- Medium-voltage resource that provides a very high current, time-limited current pulse in a fully floating mode.

17. RCS:「Ramp Current Source」 --- Generates ramp current with controlled duration, synced from the regulator device under test.

18. TIA: 「Time Interval Analyzer」 --- Two-channel, high-precision time measurement instrument mounted in the PC case.

19. TMU: 「Time Measurement Unit」 --- Flexible card that gives a wide range of timing measurement functions for both analog and digital devices.

Minimum instrument configuration requires one DVI Dual Voltage/Current card in slot 9, and one MUX Multiplex Relay card in slot 20. These DVI and MUX cards are used during calibration and verification of the tester. Other instrument cards are added to expand the system as required.
