The SR192 integrates both bus emulation and traditional stimulus/response capability in a single package. The SR192 provides the following features:

VERSATILE ARCHITECTURE....The SR192 is message based with A32 addressing for high speed downloading and retrieving of test data. In bus emulation mode channels are grouped in 8 pin groups as fields of 8, 16, 32, etc. In stimulus/response mode, each of the channels can be input or output (per pin architecture).

DENSITY....VXI space is at a premium, thus the SR192 was designed to pack the most dynamic digital capability in the smallest possible space.192 I/O channels with 128K bits per channel plus 20 additional timing and control signals are housed in a dual slot “C” size VXI module.

MODULARITY....The SR192 was designed as a motherboard/daughterboards arrangement. With this concept the user purchases the number and type of I/O channels needed for his test requirements. The system can easily be upgraded at a later time as test requirements change. Multiple SR192’s may be installed in a VXI chassis and linked in a master/slave configuration up to 1152 I/O channels.

DRIVER/RECEIVER VOLTAGE FAMILIES....The SR192 offers a variety of I/O daughterboards with options such as, TTL single-ended, 422/485 and ECL differential, variable voltage modules with ranges from +15V to -15V or +7V to -5V. Most modules can be mixed in a single SR192 to provide more flexibility for the user.

PROGRAMMING....The SR192 is a message based SCPI compatible module with A32 addressing capability. It is shipped with VXI Plug&Play drivers and soft front panel. Graphical editor software packages are available as options allowing an easy means of programming timing and stimulus data.

SR211 PROBE....The SR211 probe is 25MHz dual threshold data probe. It consists of an external pod, which houses all probe related electronics, and a standard X10 scope probe. This eliminates the high cost of maintenance and service associated with custom digital probes. Real time node status is visually shown via 5 LEDs located on the pod, ( “Good One’, “Good Zero”, Tristate, Contact or Pulse signals are indicated). The SR211 features +/- 10Vdc threshold setting with 20mV resolution, static voltage reading and 128K bits of memory for data capture. The SR211 may be used in a manual mode with data capture initiated via a scope probe button or with the Millennia III prober in a fully automated mode..

For systems with 6 I/O modules or less, a minimum of one timing set module is required. For systems with 7 I/O modules or more, two timing set modules are required. These timing set modules are nearly identical to Talon's BE-64 timing sets. They include handshake control signals, programmable cell delay, and a programmable time-out function. They may be clocked at frequencies to 50MHZ, yielding 20 nsec resolution for UUT control signals, bus enable signals, input sample signals, etc. The two timing set modules may operate completely independent and asynchronous from one another, yielding two independent interfaces, each having up to 96 I/O channels.

TTL I/O Modules

Differential Modules

Variable Voltage I/O Modules

The +/- 15V I/O modules for the SR192 utilize the SR210 Accessory Module to program the threshold references for the drivers and receivers. The SR192 provides three voltage families referred to as VGRPI, VGRP2 and VGRP3. VGRP1 . Each family may be independently programmed to a different voltage level. External power for the drivers and receivers is provided through the SR192 front panel J10 connector. The VXI platform does not provide sufficient power to utilize the +/- 15V capability of the modules.

The SR214 I/O modules for the SR192 utilize the SR210 Accessory Module to program the threshold references for the drivers and receivers. The SR192 provides two voltage reference families, REFA and REFB. Each family may be independently programmed to a different voltage level and both are routed to the SR214 drivers and receivers. The user assigns drivers and receivers to REFA or REFB in groups of 8 channels. External power for the drivers and receivers is provided through the SR192 front panel J10 connector. The VXI platform does not provide sufficient power to utilize the full +7 to -5 voltage swing capability of the SR214 modules.

Timing and Accessory Modules

SR100    The SR100 provides all timing and output enable/input response strobe-control for the SR192 I/O modules. The SR100 supports 128 cells (clock periods), 64 timing sets, 4 subsequences, single, loop and continuous sequencing. The timing module is required for all I/O modules. For each 6 I/O modules, a new timing module is required.

SR101    The SR101 provides all timing and output enable/input response strobe-control for the SR192 I/O modules. The SR101 supports 256 cells (clock periods), 64 timing sets, 128k subsequences, single, loop and continuous sequencing. The SR101 also supports conditional and non-conditional jumping, looping and gosubs. The timing module is required for all I/O modules. For each 6 I/O modules, a new timing module is required.

SR210    The SR210 Accessory module provides three separate input/output - reference groups for setting the  input and output thresholds for the variable voltage I/O modules. It also provides two internal 0-50 Mhz programmable clock sources for programming the timing modules or external use and interface signals for the SR211 probe.

SR211    The SR211 is a high speed 25 MHz dual threshold single data probe. The SR211 replaces the SR111 single threshold data probe. The SR211 consists of an external pod, which houses all probe related electronics, an SR192 I/O interface card, 6 ft. interfacecable between the SR192 and SR211 pod and a standard X10 scope probe. Real time node status is visually shown via 5 LED’s located on the SR211 pod. Standard features include: +/- 10 vdc threshold setting with 20mV resolution, 25 MHz data rate capture, static voltage reading, data capture initiated via scope button or SR211 pod button, pulse detect (>10ns).
