1.1 General

Usage
Features of the R&S TS-PSAM
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 mea­surements, 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 Lab­Windows 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 – ±5 V, 100 mA max.
fast settling time
four-quadrant operation
sense wires

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 measure­ments. The measurement unit and the adjustable DC voltage source are cross-connec­ted 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.

1.2.2.2 ICT Measurements with R&S TS-PICT
Usage
Features of the R&S TS-PSAM
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 TS­PSAM 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)

Layout
Mechanical Construction of the R&S TS-PSAM
On this topic, see also Figure 4-1.
The R&S TS-PSAM module is designed as a long cPCI plug-in module for mounting in the front of the R&S CompactTSVP. The board height of the module is 3 HU (134 mm). To ensure that it is inserted correctly into the Compact TSVP, the front panel is fur­nished with a locating pin. The module is secured in place with the two retaining screws on the front panel. Front connector X10 is used for connecting the UUTs. Con­nector X30 connects the R&S TS-PSAM module to the analog bus backplane in the R&S CompactTSVP. Connectors X20/X1 connect the R&S TS-PSAM module to the cPCI backplane/PXI control backplane.
