M9195B hardware overview
Individual channel capability
Each of the 16 bidirectional channels provide programmable logic levels of –1.5 V to +6.5 V with
152 μV resolution. The per channel 4 quadrant parametric measurement unit (PPMU) enables
FVMI, FIMV, FVMV, and FIMI and FNMV modes. With the 5 PPMU current ranges between
±2 μA to ±40 mA, users can make accurate leakage measurements.
Each channel can be configured for parametric measurements, as a static digital I/O pin, or
with synchronized cyclized digital data. Digital channel direction and timing can be flexibly
controlled on a per digital vector basis. The cyclized data allows each pin to operate in RZ or
NRZ modes. In combination with the 1 ns edge placement resolution, each pin allows for an
adjustable output delay, for timing margin testing, and receive delay to compensate for cabling
propagation delays.
Multi-site capability
The PXI DSR provides a choice of a single-site configuration with 16 synchronized channels,
or a multi-site configuration with 4 sets of 4 synchronized channels. In multi-site mode, each
site has its own independent sequencer. This enables site independent clock operation for
simultaneous testing. The multi-site capability simplifies test development. Instead of forcing
the test engineer to create a single test that encompasses all for sites simultaneously, the user
only needs to focus on a single device. The single device test can be easily replicated for the
remaining test sites. In addition to the digital pins, each site has a high voltage drive channel
and an open drain control channel for relay control.
Multi-module synchronization
Up to 12 modules can be combined to build systems up to 192 channels (requires opt MMS for
each module plus the appropriate sync cable, either Y1250A or Y1251A). When modules are
combined, they operate in single-site mode and all channels are synchronized to a single test
sequencer. Typical channel-to-channel skew (including across modules) is ±300 ps. Multiple
modules are combined and programmed together into a single multi-module instrument.
Per-Pin Parametric Measurement Unit (PPMU)
The PPMU feature, available on each of the PXI DSR’s 16 channels, enables DC current and
voltage measurements. Each channel can be independently programmed to force a voltage
and measure the corresponding current, or force a current and measure the voltage. The PPMU
can make leakage current measurements at low current ranges or for measuring low input
resistance in high current ranges. In a force voltage/measure current (FVMI) mode the PPMU
can measure input bias current on a single DUT pin. For high current applications, each channel
has remote sense capability to account for the
voltage drop across the connecting cable.
Perform continuity testing of a DUT by forcing
current into the pin with other DUT pins
grounded while measuring the voltage at the
pin (FIMV). The FNMV mode (Force Nothing,
Measure Voltage) enables the PPMU to be
used as a scanning voltmeter. The PPMU
provides built-in 64 sample, 50 Hz or 60 Hz
averaging to improve measurement quality by
rejecting power line noise. All PPMU channels
share a 16-bit measurement subsystem for fast
accurate measurements.
