M9195A 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 (PMU) enables FVMI, FIMV, FVMV, and FIMI and FNMV modes. With the 5 PMU
current ranges between ±2 μA to ±40 mA, users can make accurate leakage measure-
ments.
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 devel-
opment. 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.
Parametric Measurement Unit (PMU)
The PMU feature, available on each of the PXI DSR’s 16 channels, enables DC current
and voltage measurements. The PMUs can be independently programmed to force a
voltage and measure the corresponding current, or force a current and measure the
voltage. The PMU 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 PMU 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 Noth-
ing, Measure Voltage) enables the PMU to be used as a scanning voltmeter. The PMU
provides built-in 64 sample, 50 Hz or 60 Hz
averaging to improve measurement quality
by rejecting power line noise. The PMUs
share a 16-bit measurement subsystem for
fast accurate measurements.
