  • Page 18: Typical Applications

    ® Typical applications R&S TS-PIO4 Digital functional test – static 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.

  • Page 19: Digital Functional Test - Dynamic

    ® Typical applications R&S TS-PIO4 Digital functional test – dynamic 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.

  • Page 20: Functions

    ® Functions R&S TS-PIO4 Overview 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.

  • Page 21: Ports

    ® Functions R&S TS-PIO4 Overview 7.1.2 Ports Due to the structures in the hardware, the digital inputs and outputs are divided into so‑called ports. The R&S TS-PIO4 module provides 32 outputs (OUT1 to OUT32) and 32 inputs (IN1 to IN32). Each port (PORT0 to PORT7) is made up of 4 channels. Many functions of the driver refer to this port structure.
  • Page 22 ® Functions R&S TS-PIO4 Overview For reasons of backward compatibility, the attribute RSPIO4_ATTR_PORT_HANDLING can be set to the value RSPIO4_PORT_HANDLING_PDFT using the rspio4_ConfigurePortHandling function. In this case, the driver software emu- lates a module with 4 ports each with 8 channels. With this setting, the tri‑state infor- mation in the data structures is interpreted on a port‑specific basis.

    ® Functions R&S TS-PIO4 Configuration of digital channels 7.2.2.6 Execution of pattern set The pattern set can be executed synchronously or asynchronously. In the first case, the DIOMGR_ExecutePatternSet() function does not return until execution has been completed (or the maximum time has been exceeded). In the second case, exe- cution is started or the trigger armed and the function returns without having to wait for actual execution of the pattern set.

This safety circuit has the following structure: Figure 7-3: Configuration of input channels Each input is routed to two comparators which have an adjustable threshold.

  • Page 35: Time Settings For Data Output

    ® Functions R&S TS-PIO4 Configuration of digital channels If the comparator is set to "COMP" mode, the two comparators function as window comparators. A 1 is detected if the input level is between the thresholds, and a 0 is detected if the input level is below the threshold for low or above the threshold for high. 7.3.4 Time settings for data output This setting is required both for dynamic tests in compliance with IVI Digital and for dynamic tests with the low‑level driver functions.
  • Page 36 ® Functions R&S TS-PIO4 Configuration of digital channels ● rspio4_ConfigureRespMode If required, the digital channels can be configured in different combinations for simulta- neous static and dynamic operation. This, for example, allows the configuration of con- trol signals that remain at a constant level during entire test sequences. They then no longer have to be part of the dynamic data.

    ® Functions R&S TS-PIO4 Triggering and sequence control The output of the trigger unit is used to actuate other functions. Selection of a certain type of output signal does not influence the internal function (output stimulus, read in response). This output signal (e.g. ACTIVE) can be output on the PXI0 to 7 lines as well as on XTO in order to, for example, trigger a measurement on a different CompactPCI board.

    ® Functions R&S TS-PIO4 Bidirectional channels ● If a defined number of pulses (gateCounts) is specified, the module measures the time required for a certain number of pulses to arrive. The Gate Time parameter is considered a timeout value. If the desired number of pulses is not included into this time, the rspio4_FrequencyMeasurement function will return an error mes- sage.
