3 Welcome to the R&S TS-PIO4
This manual describes the function and operation of the Rohde & Schwarz digital func-
tional test module R&S TS-PIO4 for use in the test system versatile platform
R&S TSVP. The module is controlled by the PXI bus and occupies one slot on the front
side of the R&S TSVP.
The R&S TS-PIO4 digital functional test module is used wherever digital circuits are
tested by flexibly programmable static or dynamic stimulation and the response is
recorded.
Deterministic, simultaneous stimulation and recording of digital signals makes it possi-
ble to simulate operating conditions in a manner that is very close to reality. A large
local memory pool and an independent sequence controller are available on the mod-
ule to ensure that the precise and predictable time response can be maintained for out-
put, recording and analysis of the bit patterns. Extensive trigger options via the PXI
trigger bus enable synchronization with additional R&S TS-PIO4 modules or other
measurement and stimulus modules. This makes it possible to increase the number of
digital channels in an application. Measurements in which signals are to be recorded
synchronously are also possible.
Output levels and input thresholds can be programmed in 8 ports each with 4 chan-
nels. This allows for optimum adaptability to the requirements of different logic families.
The effect of interference signals in the test setup can be minimized by adjusting the
hysteresis for the input thresholds.
Safety circuits to protect against short circuits, countervoltages and overvoltages con-
tribute to the robustness of the R&S TS-PIO4 digital functional test module. Due to the
extremely space‑saving design of the I/O safety circuit and signal conditioning unit, the
R&S TS-PIO4 occupies just one PXI slot. This makes it possible to set up very
high‑performance and compact measuring systems.
A soft panel is available for operation of the module. An IVI‑C driver is provided to
allow the module to be used under software control.
Features of the R&S TS-PIO4 digital functional test module.
●32 digital inputs and 32 digital outputs divided into 8 ports each with 4 channels
●Programmable output level range from ‒6 V to 10 V, output impedance 30 Ω (typ.)

5 Installing the module
The R&S TS-PIO4 is a module installed on the front panel of PXI based base units.
1. Install the module as described in the user manuals of the base units.
2. WARNING! Risk of electric shock. The test environment, e.g the UUT or additional
power supplies, can supply high voltages to the instruments. In this case, the volt-
age can also apply to the signal output connectors of the R&S TSVP, in particular
the analog bus connector X2.
Therefore, do not connect or disconnect devices from the X2 connectors while con-
nected to an external power supply or UUT.
Always connect both ends of the cable connecting the R&S CompactTSVP and
R&S PowerTSVP. Thus, you avoid the risk of touching the X2 connector with a
possibly hazardous voltage applied.
Take the system into operation as described in the user manuals of the base units.

6 Typical applications
The R&S TS-PIO4 digital functional test module is used for testing digital modules or
devices. This type of functional test is used to check the overall operation of a digital
circuit under conditions that are as close to reality as possible. The module does this
by applying digital input patterns, measuring the output signals and comparing them
with the nominal values.
The R&S TS-PIO4 digital functional test module can be used for tasks such as the fol-
lowing:
●Digital functional test (low‑speed/high‑speed, IO control)
●Bit pattern stimulation (low‑speed/high‑speed, digital buses)
●Bit pattern measurement (low‑speed/high‑speed)
●Monitoring of changes in level state (pattern trigger)
●Digital functional test at component level (no node‑forcing or backdriving capability)
●Downloads, e.g. for flash components, serial and parallel
A typical functional test consists of the following elements:
●Adaptation of the pin electronics to the UUT environment (logic level and logic fam-
ily)
●Definition of the sensor strobe (timing)
●Definition of the stimulus and measuring behavior
●Evaluation of the test result
6.1 Digital functional test – static
Characteristics for which correct interaction of the logic modules is more important than
the verification of time-critical limits are tested in the static digital functional test. The
application outputs the patterns to be stimulated, reads in the UUT response via the
module inputs and compares it with the expected response. Comparison with the nomi-
nal values then results in a PASS or FAIL statement. The comparison takes place in
the application. As the time response (length of time that a pattern is available; sam-
pling time point of the inputs) is controlled primarily by the host computer, this test can-
not be used to test time‑critical or chronologically precisely defined sequences. With
the static test, the order of the sequence is deterministic, i.e. the chronological order of
the patterns as well as the read‑in procedure is predictable. How long the interval from
one pattern to the next pattern will be and how large the interval from application of a
pattern to reading in of the data will be are, however, not predictable. Here, the operat-
ing system of the host computer (task switching, etc.) influences the runtimes in a
non‑predictable way.

6.2 Digital functional test – dynamic
In the real‑time test, overall operation of the digital section of a UUT is tested under
operating conditions that are as close to reality as possible. For this purpose, digital
patterns (vectors and pattern sets) with a precisely defined, usually high clock rate and
precise time response are applied at the UUT connections and the responses recor-
ded. Recording is also performed with a precisely defined, reproducible time response.
The basic requirement for exact, predictable timing is that the patterns for the stimulus
are stored in the memories "downstream of the drivers" and can be processed with a
defined time response and at a high speed. To enable this, the module has its own
sequence controller in the FPGA. The recorded input data is also initially stored in a
memory on the module and later retrieved by the application on the host computer and
evaluated for a PASS/FAIL decision.

7 Functions
7.1 Overview
7.1.1 General
The R&S TS-PIO4 digital functional test module provides 8 ports each with 4 digital
input pins and output pins. For this purpose, the module has unmultiplexed digital pins,
i.e. behind each pin is a separate digital channel. Furthermore, the output voltages of
the drivers as well as the comparator thresholds of the inputs can, within certain limits,
be freely programmed on the module. This allows the appropriate logic level to be gen-
erated for practically every application. All settings as well as clock generation take
place on the module itself, which means that no additional stimulus modules are nec-
essary.
Refer to Figure B-1, Figure B-2 and Figure B-3 for details.
The usable level range depends on the configuration of the driver references. The
overall level range is divided into 4 sections. The driver levels are generated from the
CPCI supply (+5 V and +3.3 V).
The application software must set an appropriate voltage range before the output vol-
tages and comparator thresholds can be configured. Here, the device driver performs a
plausibility check and prevents invalid or damaging values from being set.

Range VL1VH2CVL3 / CVH4
3 +1.5 V to +6.0 V +1.5 V to +10.0 V +1.5 V to +7.1 V
2 ‒1.8 V to +2.7 V ‒1.8 V to +10.0 V ‒1.8 V to +7.1 V
1 ‒3.5 V to +1.0 V ‒3.5 V to +10.0 V ‒3.5 V to +7.1 V
0 ‒6.0 V to ‒1.5 V ‒6.0 V to +8.0 V ‒6.0 V to +5.1 V
1VL: Output level Low
2VH: Output level High
3CVL: Comparator level Low
4CVH: Comparator level High
If required, all outputs (OUTx) can be connected to their corresponding input (INx) and
therefore stimulate, measure and monitor the driving of signals. All driver channels can
be set to the high‑impedance state (TRI-STATE).
Timing control of data output and reading in of response signals takes place on the
module controlled by FPGAs.
