The Marvin Test MV-GX5961 digital subsystem card represents the highest level of performance available for PXI-based digital instrumentation. Based on the proven architecture of the MV-GX5055 and the EADS T964, the MV-GX5961 offers high performance pin electronics and a timing generator / sequencer in a compact, 6U PXI form factor. The MV-GX5961 consists of one MV-GX5961 Clock generator board with 16 driver / sensor channels and the MV-GX5964 driver / sensor board which supports 32 bi-directional I/O channels. Up to 528 digital I/O channels can be supported by the MV-GX5960 digital subsystem. Each digital channel features a wide drive / sense voltage range of -15 V to +25 V (maximum swing of 26 volts) which can be individually programmed for a drive hi, drive lo, sense hi, sense lo, and a load value (with commutation voltage level) €“ offering the user complete flexibility when creating test programs and fixtures for multiple UUTs. In addition, each channel offers a parametric measurement unit (PMU) for DC measurements.
The Marvin Test MV-GX5960 offers real-time digital stimulus, record, or expect data modes on all I/O channels. Pattern memory depth is 256K words. Each channel can be configured as an input or output on a per cycle basis. Six drive data formats are supported: NR, R1, R0, RZ, RC, and Complement Surround €“ providing flexibility to create a variety of bus cycles and waveforms to test board and box level products.
The MV-GX5961 provides timing, input / output synchronization signals, and sequencing as well as 16 I/O channels. Additional channels can be added to the system by installing one or more, MV-GX5964 boards which are interconnected via the PXI local and trigger busses. The MV-GX5961 offers a flexible clock system which allows the module to operate as a timing master to the UUT or be slaved to the UUT€™s time base or some other external clock.
All pin electronic resources are independent on a per channel basis €“ offering the user complete flexibility when programming drive / sense levels, source / sink currents, slew rate, skew, or PMU functions. The PMU can operate in the force voltage / measure current or force current / measure voltage mode and is useful for measuring a UUT€™s DC characteristics. In addition, each I/O channel includes an analog bus relay, which allows each channel to support hybrid channel (digital or analog) measurement capabilities. For analog stimulus / response measurements, the analog bus can be connected to external resources via a dedicated analog bus connector located on the front panel of the module.
The MV-GX5961's sequencer supports sequences up to 4096 steps and has 16 loop counters that may be nested. The sequencer supports a variety of sequencing functions including jumps, subroutines, looping, and test inputs. All of the sequencer commands may be programmed using a Graphical Vector Editor, Windows® API commands, or via a script language. The sequencer allows the user to generate test vectors indefinitely at maximum test rates. Internal and external trigger and pause commands are available in several modes.
The MV-GX5961's timing generator supports 256 timing sets which can consist of up to 4 drive phases and 4 sense windows for 4K of sequence steps. Alternative timing set configurations include 1K of timing sets with 4 phases and 4 sense windows or 4K of timing sets with 1 phase and 1 window. The T0 cycle or sequencer period range is programmable from 20 ns to 64 µs with the phase and window values programmable from 0 ns to 64 µs. This flexibility offers the user the ability to address a wide range of applications including the emulation of complex bus cycles and proprietary digital interfaces.
