1.1 General
Use
General
1 Use
This manual describes the function and operation of the ROHDE&SCHWARZ function
generator module R&S TS-PFG for use in the test system versatile platform R&S CompactTSVP. The hardware is implemented as a CompactPCI board that occupies only
one slot on the front side of the TSVP. The associated R&S TS‑PDC rear I/O module
(DC/DC converter module) is inserted at the same slot on the rear side.
The ROHDE&SCHWARZ function generator module R&S TS-PFG can be used wherever the simulation of single‑channel or multichannel, analog output signals is required.
The floating output of the signals prevents any interference on the device under test
(DUT), thereby ensuring that the application can be simulated under conditions that are
very close to actual.
The high dynamic range of the output voltage and the high sample rate allow output
signals with an extremely high resolution to be achieved. The module can generate
standard signal forms, such as sine‑wave, square‑wave,triangular and ramp, as well as
arbitrary signal forms. These can be output continuously or in pulsed mode.
Commercially available waveform editors can be used for defining the signal curves
(e.g. Analog Waveform Editor from National Instruments). Comprehensive trigger
options with local trigger and marker signals or the PXI trigger bus enable synchronization with other R&S measurement, stimulus or switch modules and PXI modules from
other manufacturers.
A LabWindows IVI‑C software driver is available for the general waveform generation
functions of the R&S TS-PFG module. Other hardware functions are controlled using
specific extensions of the driver. As is usual for a LabWindows driver, function panels
and online help are available.
The R&S TS-PFG module is inserted into the front of the R&S CompactTSVP chassis.
It uses the cPCI/PXI standard. The front connector is flush with the front panel of the
R&S CompactTSVP chassis and is used for connecting DUTs or measurement sensors. At the back, the R&S TS-PFG module is connected to the cPCI control bus and
the PXI trigger bus. As an alternative to the front connector, analog measurement signals can be tapped at the analog measurement bus of the R&S CompactTSVP.
The voltage supply of the R&S TS-PFG is made available to the module via the
R&S TS‑PDC rear I/O module with DC/DC converters.
The R&S TS-PFG module can only be used in the R&S CompactTSVP (TSVP = Test
System Versatile Platform).

Use
1.3 Possible Applications
The R&S TS-PFG function generator module can be used for tasks such as the following:
●
Generation of sine‑wave, square‑wave, ramp and triangular signals
●
Generation of concatenated waveforms of any type
●
Sensor simulation (floating stimulation)
●
Generation of arbitrary signals
●
Stimulation of low‑frequency digital signals with variable level
●
Programmable clock‑pulse generators
●
Generation of DUT supply voltages
If the application requires additional stimulus channels, this can be achieved by adding
further R&S TS-PFG function generator modules and synchronizing them via the PXI
trigger bus.
The analog bus and a R&S switching module (e.g. R&S TS‑PMB) can be used to multiplex the output signals over a very high number of DUT pins.
Complex test operations can be performed using the digital marker signal which is output sample‑synchronously with the analog signal. Using a switchable connection of the
two output channels, the output voltage range can be doubled and/or DC signals generated with up‑modulated AC signals.

1.4 Safety Instructions
Use
Safety Instructions
The extremely compact design with primary matrix and signal conditioning occupies
just a single CompactPCI/PXI slot width, making it possible to create space‑saving yet
very powerful measurement and stimulus systems.
A self-test of the R&S TS-PFG function generator can be run in conjunction with the
R&S TS‑PSAM analog measurement and stimulus module. Diagnostic LEDs in the
front panel indicate the current status of the module.
Damage to device or individual modules due to excessive operating voltage
The R&S CompactTSVP/R&S PowerTSVP production test platform and the
R&S TS‑PFG function generator module are designed for operating voltages up to
125 V. If this operating voltage is exceeded, the device and the individual modules can
be damaged.
It is also important to ensure that this limit is not exceeded at any time, even after summation of voltages, between floating measurement or stimulus instruments and GND.
Risk of injury from electric voltage
To prevent injury caused by electric voltage, it is important to observe the requirements
specified in EN61010‑1 concerning operation with "hazardous active" voltages.
Figure 1-1 shows a number of typical permissible voltage configurations between the
analog buses and ground.

The R&S TS‑PDC module is a rear I/O module for mounting in the back of the
R&S CompactTSVP. The height of the module's board is 3 HU (134 mm). The module
is secured using the two fastening screws on the front panel. Connector X20 connects
the R&S TS‑PDC module to the backplane in the R&S CompactTSVP.
Damage to R&S TS‑PFG and R&S TS‑PDC modules
Incorrect connection of the R&S TS‑PFG and R&S TS‑PDC modules to the backplane
of the R&S CompactTSVP can result in damage to the two modules.
