An important feature of the ETS-800 is the Adaptive Pin Expansion (APEx) architecture, which enables economical site count expansion. The power of APEx is that it allows the test system to stretch to higher site counts through resource sharing, while minimizing DIB based switching circuitry and saving valuable application space. The APEx architecture provides built-in signal multiplexing distributed throughout the various resources of the system.
Analog Pin Unit 32 (APU-32) is a single slot, 32 channel, 80 V, four quadrant V/I with eight current ranges (from 200 mA to 1 µA) and per-pin AWG and digitizing capabilities.
Capacitance Application Module (CAM II) is an application-specific resource module designed to measure extremely low capacitance levels in the sub-picofarad range. The CAM II can be used across all ETS series test platforms and all FLEX series test platforms.
The High Speed Digital 32 (HSD-32) is a single-slot, high speed digital instrument containing 32 independently programmable I/O channels, organized as two separate 16 channel subsystems. HSD-32 provides time measurement capabilities for ETS-800 test systems using the Time Stamper Unit (TSU).
The Medium Current Multiplexer (MCMUX) board resides in the test head and provides 64:1x4 solid state pattern controlled multiplexers. This board allows the user to distribute instrument pins to multiple DIB pins, reducing the number of instruments required for a typical multisite test application.
The Picoamp Module (PAM) is an application-specific instrument module designed to force voltage and measure subnanoamp currents. The PAM can be used across all ETS series tester platforms.
The QMS-T instrument (shown above in an FR carrier board for use in an ETS-800 system) provides four independent floating differential voltmeters for measuring both DC and AC signals. Each channel offers nine voltage ranges from ±200 V to ±0.5 V with optional use of either a 10 Msps 12-bit digitizer or a 200 ksps 16-bit digitizer.
The SPU-2112 Mux Booster Board (SPMB-2112) is an optional booster instrument that enables the SPU-2112 to deliver extended pulse current capability. A high current booster cable connects one booster channel to one SPU-2112 channel. Each booster board can supply high current pulse power to eight SPU-2112 channels (two SPU-2112 boards). The SPMB-2112 also includes 16:1x4 solid state pattern controlled multiplexers which support the full SPU-2112 operating range. Each channel is fully isolated (80 Vrms) from pin-to-pin and pin-to-ground.
The SmartPin Unit 100 V/10 A (SPU-2112) is a single-slot, quad-channel, ±100 V SmartPin with eight current ranges. The SPU-2112 spans a wide range of voltage and current combinations, making it an extremely versatile instrument. The SmartPin architecture incorporates an AWG and a digitizer within a conventional four quadrant V/I.
The Utility Pin Unit 64 (UPU-64) is a 64-channel multi-function instrument organized in four independent banks of 16 channels. Each bank consists of 16 20 MHz high voltage digital channels (-1 V to +24 V), four time stampers, and two dual 2x8 force/sense cross-point APEx multiplexer. Each digital channel includes an integrated PPMU, a dynamic load, multiplexed access to four local time stampers, remote measure voltage capability, and access to the 2x8 APEx matrix.
