| TA320S - Description and Specifications |
A specification
far in excess of its price
The TA320 has a specification that meets the needs of all but the most
demanding of applications. 32 data channels, 100MHz maximum acquisition
speed, 5ns glitch capture and multi-level trigger sequencing.
An essential instrument in every area
The capabilities of a logic analyser have become important within
virtually every area of electronics. Development, production, service and
education all have a need for logic analysis but the high prices have
discouraged many potential purchasers. Now TTi have made high performance
logic analysers affordable.
32 channels and a 2K word memory
The TA320 has 32 data channels and a 2K word data acquisition memory.
This enables it to
capture and analyse relatively complex data including disassembly of a
range of popular microprocessors. |

100MHz asynchronous acquisition
When making timing measurements you need as much speed as you can get, so
the TA320 gives you a full 100MHz on 8 channels when used with high speed
pods.
5ns glitch capture
Glitch capture allows you to see very short pulses which are beyond the
resolution of the analyser's sample clock. The TA320 enables you to detect
glitches down to 5ns on 16 channels and provides glitch trigger, a very
important facility for finding some types of fault.
Multi-level trigger sequencing
The most important requirement of a logic analyser is that it should
capture exactly the data that you need. That requires sophisticated
triggering. The TA320 gives you a four step sequencer with event counting
and restart on each step. Trigger words are full width and the trigger
position within the store can be varied.

SPECIFICATIONS
SIGNAL INPUTS
Data Channels: 32
Clock Inputs: 3 independent clock inputs; active edge can be independently
selected for each to be either positive, negative or off.
Clock Qualifiers: 3 qualifier inputs, 1 for each clock. Selectable to be
active high, low or don't care.
Input Characteristics: Determined by the type of pod fitted; requires
either one AP01, or two AP03s plus one AP04, or two AP03Vs plus one AP04V.
See PODS section.
Activity Indicator: Shows whether the channel input is high, low or
switching.
MEMORY ORGANISATION
Data Memory Size: 32 bits x 2K words
Reference Memory: 32 bits x 2K words
Non-volatile Memory: Non-volatile storage for 10 acquisitions and 10
set-ups. Data retention typically 5yrs by lithium cell.
EXTERNAL CLOCK
Frequency Range: DC to 25MHz
Clock Pulse Width: 20ns minimum
Organisation: 3 clocks, individually qualified and ORed together.
Set-up & Hold Times: 18ns set-up, 0ns hold for both data and clock
qualifiers.
INTERNAL CLOCK
Clock Rate: Selectable 40ns to 100ms (25MHz to 10Hz) in a 1:2:4 sequence
with all pods. Additionally 10ns (100MHz) in high speed mode with high
speed pod.
TRIGGERING
Sequencer Words: 4 words of up to 32 bits.
Sequencer Terms: The actual trigger term searched for in a sequencer step
each consist of up to 4 trigger sequencer words ORed together.
Sequencer Steps: Each of up to 4 sequencer steps consists of a search for
the trigger term specified in that step. Each step has an event count of 1
to 128 occurrences of the trigger term.
Trigger Position: Selectable to be from 0 to 5K clocks before the start,
centre or end of store, settable in 1K steps.
Trigger Output: TTL level signal at rear panel BNC
GLITCH (Only available with high speed pods).
Number of Channels: 16 (8 per pod)
Detectable Pulse: 5ns minimum
Glitch Triggering: A glitch word can be specified which can be ORed with
any trigger word within a trigger term.
TIMING DISPLAY
Number of Channels:
TA320S - Any 6 channels may be displayed; channels may be repeated.
TA320PC - Any 16 channels may be displayed; channels may be repeated.
Channel Labelling:
A user-defined name can be given for each group of channels and each
channel will be uniquely numbered within the group.
Number of Samples:
The store can be displayed with expansions of x1,x2,x4,x8,x16. Window
indicator shows position of window within the store and shows expansion.
Expansion window scrolled throughout store.
Cursors:
Movable cursor and marker, with readout of store positions and data
values. Marker moves to the trigger location following each acquisition.
Search: A search can be made for any word; the search word may include
glitches.
Glitches: Shown by markers on the appropriate data channels.
LIST DISPLAY
Channel Groups:
Up to 32 channels can be grouped together under a single character label
for which a name can be defined. Up to 16 groups can be specified.
Display Format:
Binary, Octal, Hex, Decimal or ASCII individually selectable for each
channel group. Each group is listed underneath its label or name.
Cursors:
A movable cursor and a fixed marker are provided.
Search & Compare:
Differences between data and reference can be shown and a search made for
any word and any difference. Automatic comparisons can be performed on a
user specified area of the data and acquisitions stopped on an equality or
inequality.
HARD COPY OUTPUT
