1.1 General
The R&S TS-PSAM Analog Stimulus and Measurement Module is suitable for the R&S
CompactTSVP. The module is used to perform analog measuring tasks, in-circuit mea-
surements, and the R&S CompactTSVP self-test. The module's floating DC supply
voltage is provided via the associated R&S TS-PDC rear I/O module.
The R&S TS-PSAM module is inserted in the front of the R&S CompactTSVP chassis.
It is based on the cPCI/PXI standard.
The front connector ends flush with the front panel of the R&S CompactTSVP chassis
and is used for contacting the test products or measurement sensors. At the back, the
R&S TS-PSAM module is connected to the cPCI control bus and the PXI trigger bus.
Instead of using the front connector, measurement signals can be routed via the R&S
CompactTSVP's analog measuring bus.
A LabWindows IVI DMM driver is provided for the DMM functions on the card. All other
functions are controlled using specific extensions of the driver. As is typical for a Lab-
Windows CVI driver, Function Panels and Online Help are available.
1.2 Features of the R&S TS-PSAM
1.2.1 Components
The R&S TS-PSAM modules include a ground-connected discharge circuit, a floating
programmable voltage source, and a floating measurement unit. These components
can be switched to the R&S CompactTSVP's analog bus via a relay matrix. Measuring
tasks can be synchronized using the trigger lines across the PXI bus and the trigger
inputs on the front connector. Two relay multiplexers with four channels each are also
provided. The major features of these three function blocks is explained in detail in the
following section:
floating DC voltage source (DCS)
●adjustable voltage and current limiting

1.2.2 Measuring Functions
The module is used to perform analog measuring tasks, in-circuit measurements, and
the R&S CompactTSVP self-test. In these tests, the module functions as a measuring
device with adjustable sampling rate for voltage, current and resistance measure-
ments. The measurement unit and the adjustable DC voltage source are cross-connec-
ted with each other in a suitable manner for measuring resistance. If necessary, the
source can also be connected with GND. The measurement unit and the DC voltage
source can also be operated independently of one another. In the in-circuit test (ICT),
the R&S TS-PSAM module performs the following measuring tasks:
●Discharging capacitors
●2- and 4-wire resistance measurements (Figure 1-1 to Figure 1-4)
●Contact test
●Short circuit test
●Connection test
1.2.2.1 Resistance Measurements
On this topic, see also Figure 1-1 to Figure 1-4.
Resistance measurements are taken with the aid of the DC voltage source and the
measurement unit. 2- and 4-wire measurements are possible. Two different procedures
may be followed depending on the resistance value to be measured. If necessary, the
source can be connected to GND.
●Mode C for small resistances

1.2.2.2 ICT Measurements with R&S TS-PICT
On this topic, see also Figure 1-5 and Figure 1-6.
Further in-circuit measurements can be made in conjunction with the R&S TS-PICT
module (ICT expansion module). These are:
●Diode and transistor test
●Guarded resistance measurements (3, 4 and 6 wires)
●Impedance measurements (3, 4 and 6 wires)
For this purpose, the R&S TS-PICT module provides a special AC voltage source
(AOS) and current measurement unit (CMU).
The UUT is connected for the in-circuit test (ICT) via the R&S TS-PMB module (matrix
module B).

1.3 R&S TS-PDC Features
The R&S TS-PDC module is used as a floating DC voltage source for the R&S TS-
PSAM module. It is configured with two identical DC/DC converters. The following
floating direct voltages are obtained from an input voltage of 5 VDC:
●+15 VDC ±5%, 0,5A (2x)
●-15 VDC ±5%, 0,5A (2x)
●+5 VDC ±5%, 0,5A (2x)
●+3,3 VDC ±5%, 0,25A (2x)
