SR192A TALON VXI DIGITAL MODULE
8 to 192 Bi-Directional Channels in 2 Slots
Data Rates from DC to 50 MHz
Programmable Clock 10 Hz to 100 MHz
I/O Modules TTL, RS485, LVDS or +7 V to –5 V
Variable Voltage Levels Assigned in 8
Channel Groups
The SR192A is based on Talon Instruments extremely successful SR192. For existing SR192 users, the SR192A is very similar in operation but adds a number of very powerful features:
Vector bus –
A 4-bit address bus that can be used to trigger a specific table output form the I/O module. The 4 bits may be user selected from any of the 96 channels of a particular timing generator group. The data will be output on the next data cycle after receipt of the vector address.
Handshake bus –
Allows the user to select any of the 192 channels as a test input for the timing generator. Inputs may be tested for high, low, rising or falling edges. Two channels on each timing generator may be selected as test input channels during any test.
Clock Resolution –
The SR101A timing module may be clocked on both edges of the system clock allowing for better timing set resolution.
Timing Set Clock –
A new programmable clock source has been added to the SR101A Strobes/Enables – the number of strobes/enables has been increased from 4 to 6.
I/O Modules-
The user is required to select from 1 to 12 I/O modules for the SR192A. Talon manufactures the following type of I/O modules for the SR192A:
SR124A – 8 channels of bi-directional TTL or RS422/RS485
SR125A – 16 channels of bi-directional TTL
SR126A – 8 channels of bi-directional LVDS

Stimulus/Response Testing
For test applications where test vectors are available, the Model BE-64 can be programmed to transmit or receive 64 channels by 32K bits per channel at frequencies to 25 Mhz.
Bus Structured Interface Simulation
Bus structured interfaces are simulated exactly like the bus structured interface of a microprocessor. The architecture of the BE-64 has enabled Talon customers to simulate well over 1000 different digital interfaces. These interfaces range from a serial T2 communication interface to a high speed VME bus structured interface. Talon offers set up configurations for the following bus structured interfaces: VME bus, VXI bus, Multibus, AT bus, NuBus, SCSI bus, Microchannel, EISA bus, S bus.
