FUNCTION
30
51
DUTHA
PMU-A Window-Comparator High-Comparator Output. A sense-A voltage above the VTHMAXA
level forces the DUTHA output low. DUTHA is an open-drain output.
31
50
HI-ZB PMU-B MSRB Output State Control. A logic low places the MSRB output in a high-impedance
state.
32
49
HI-ZA PMU-A MSRA Output State Control. A logic low places the MSRA output in a high-impedance
state.
35
46
RXAA PMU-A Current-Range Sense-Resistor Connection. Connects to the external current-range
sense resistor on the amplifier side for PMU-A. See Figure 5.
36
45
RXDA
PMU-A Current-Range Sense-Resistor Connection. Connects to the external current-range
sense resistor on the DUT side for PMU-A. See Figure 5.
37
44
CC2A
PMU-A Compensation Capacitor Connection 2. Provides compensation for the PMU-A main
amplifier.
38
43
CC1A PMU-A Compensation Capacitor Connection 1. Provides compensation for the PMU-A main
amplifier.
39
42
SENSEA PMU-A Sense Input. A Kelvin connection to the DUT. Provides the feedback signal in FVMI
mode and the measured signal in FIMV mode for PMU-A.
40
41
FORCEA PMU-A Driver Output. Forces a current or voltage to the DUT for PMU-A.

RAE PMU-A Range E Resistor Connection
46
35
RACOM
PMU-A Range-Setting-Resistor Common Connection. Connect to one end of all range-setting
resistors (RA_) for PMU-A. Also serves as the input to an external current range buffer for PMU-A.
49
32
THMAXA PMU-A Window-Comparator Upper Threshold Voltage Input. Sets the upper voltage threshold
for the PMU-A window comparator.
50
31
THMINA
PMU-A Window-Comparator Lower Threshold Voltage Input. Sets the lower voltage threshold
for the PMU-A window comparator.
51
30
CLHIA PMU-A Upper Clamp Voltage Input. Sets the upper clamp voltage level for PMU-A.
52
29
CLLOA PMU-A Lower Clamp Voltage Input. Sets the lower clamp voltage level for PMU-A.
53
28
IN0A
Input Voltage 0 for PMU-A. Sets the forced current in FI mode or the forced voltage in FV
mode for PMU-A.
54
27
IN1A
Input Voltage 1 for PMU-A. Sets the forced voltage in FV mode or the forced current in FI
mode for PMU-A.
PMU-A Measurement Output. Provides a voltage equal to the SENSE voltage in FIMV mode
55
26
MSRA and provides a voltage proportional to the DUT current in FVMI mode for PMU-A. Force HI-ZA
low to place MSRA in a high-impedance state.
56
25
IOS Offset Voltage Input. Sets an offset voltage for the internal current-sense amplifier for both
PMU-A and -B.
