64 channels now).
6
Note: It can Expand to 64 channels when the two LA-2132 Series connect together
By one 20 pins flat cable (But LA-2132 LVDS can not Expand to 64 channels).
Please take a notice in order to support enough current, it is better to use
2 head of Special USB 2.0 cable insert to USB 2.0 port of your computer.
Guide To Operations
Hardware
When making measurements with the Logic Analyzer, meaningful data can only be captured
with some prior knowledge of the characteristics of the circuit under test.
Before initiating any capture cycles, the Logic Analyzer must be configured using the control
program. See the software section later in the manual for instructions on these procedures.
To connect the Logic Analyzer to the test circuit, a series of mini-clips on the Logic Analyzer
input channels. The LA-2132 Logic Analyzer has inputs for 32 channels ch0 to ch31.
the ch31 channel is the external clock input.
At times, it may also be necessary to connect the test circuit to the computer system itself.
This will eliminate more noise in the test application due to ground level differentials. This is
especially true when dealing with high speed timing analysis. Use a heavy gauge wire to make
a connection between the test circuit ground and the case of the computer.
Connecting Wires to Logic Analyzer
It has 64 pins [dual in line 32 pins posts]. They are organized as follows:
Right side:
00..31 Channels 0..31
ch 31
External clock input
Left side all pins are Ground connection
The wires and the clips are modular. the wires and clips can all be disconnected from each
other by gently pulling them apart. Removing just the clips, but leaving the wires connected to
the pods allows connections to be made to wires and posts of the test circuit of up to
0.64 mm (0.025 in).
Do not insert wires or posts greater than this diameter as that will expend the
contacts in the wire beyond the allowed limit, possibly damaging the connector.
7
LVDS (Low Voltage Differential Signal)
LA-2132 LVDS has another connector header [dual in line10 pins posts]
it has 4 LVDS signals 1 tri-state control input signal. 1 trigger out.
The following diagram show 2 channels bi-direction LVDS with 1 channel tri-state control
and 2 channels LVDS input signal and 1 trigger out.
/Tri-State control line is pulled low to 10 Kohm.
It can out 100 MHz and 50 MHz LVDS signal if /Tri-State is pulled high or connected to 5V.
LVDS0, LVDS1, LVDS2, LVDS3 are LVDS signal. LVDS0, LVDS1 has 1 Kohm cross it.
It also can accept LPECL signal. LVDS0 can work as external clock.
Caution: All these signals only accept 0 - 5 Volts, exceed this range will damage this
Logic Analyzer.
Vcc inhibit short to ground otherwise your computer will damage.

Multi-Window
Software open more timing if system free memory have a lot. So use 512 Mega or 1024
Mega memory will be better.
Data1- 4 to timing by point User point which timing memory should be placed for
captured data, it can let user captured 2 or 4 set different data to buffer and display, the
sequence pointed by user, this function let user have 1Mega*4 memory size.
Data1- 4 to timing by auto The same is true for it, it automatically capture 2 or 4 sets
data to buffer, the sequence is 10,9,8,7,6,5,4,3,2 then 1.
Timing1- 4<-data Activate timing display. we suggest user use more than 1 monitor to
get better show.
This software is a revolution software, it have a lot of new function, even tradition famous
oscilloscope have not these powerful function.
this software show a lot of timing, let user easy to compare and analyzer timing, tradition
software no matter it is stand alone or computer base oscilloscope only show one timing,
these one timing software only analyzer one segment of buffer, unlike this software it can
look buffer in beginning and buffer in middle and buffer in end at the same time. The
following picture part A show it is locate at beginning and part B at middle of buffer at the
same time, every individual timing also support their own cursor, voltage measurement,
zoom factor .. etc.
11
Another new function are let memory expand to 4 times by software, If memory size is 1 Mega
size, this software can let it look like have 4 Mega size when user open 4 timing and set 4 timing
by auto function. (it need 1024 Mega system memory or more). the method is software continue
capture data to these 4 timing, every timing have 1 Mega individual buffer, so user can look
almost 4 Mega memory.
it is better than any famous oscilloscope in the world. the third big function are it can show long
timing when you have two monitor, the following show two monitor long timing, it can let user
easy analyze timing, so the stand alone oscilloscope can not do it, because they only have one
monitor.
12
The fourth function is it can support two different timing at different monitor. the follow picture is
left monitor show square waveform with magnify 1 and right monitor show the waveform with
magnify 1/2. it easy compare last capture data and current data at different monitor. These
function even famous oscilloscope have not support it.
13
Capture Mode
Set trigger acquisition mode.
Single The LA looks for the trigger event. When it is found acquire a single
buffer worth of data and stop.
Normal The LA looks for the trigger event. When it is found acquire a buffer worth
of data, re-arm and repeat until stop is hit.
Auto
Similar to Normal except that it will acquire regardless of the trigger event.

A trigger word is the pattern that the Logic Analyzers needs to see before it will start to
acquire data. The trigger word is made of a series of "1", "0" and "x" (don't care) bits.
AND mode need 32 channels all match trigger condition.
OR mode need one of 32 channels match trigger condition.
It can set at toolbar or parameters form.

Logic
Trigger if condition is true or false.
True logic need trigger condition from false to true.
False logic need trigger condition from true to false.
16
How to Set Trigger Word
1) You can edit all 32 channels at a time.
Edit the pattern: The LSB is to the right. Each bit can be set to "0", "1" or "x" (don't care,
true, false).
2) You can set the trigger logic to "True" (trigger when pattern matches) or "False"
(trigger when pattern stops matching).
Trigger Position
The trigger position defines how much data is captured prior to the trigger event and how
much data stored after it. You set the Trigger position by moving the trigger cursor. This
feature allows you to see the data that led up to the trigger as well as what happened after
the trigger.
Trigger Word Setup
A sequence of up to 512 trigger words can be set. A trigger word is the pattern that the Logic
Analyzers needs to see before it will start to acquire data. The trigger word is made of a series
of "1", "0" and "x" (don't care) bits.
It can set trigger word at toolbar or parameter form or trigger form.
17
This logic analyzer support 2,8,512 trigger levels. Depend on which model user bought it,
Because logic word now is very complex, like RS232, I²C…. need a lot of trigger level to
complete it. Every trigger level support " if xx happen xx times then next level else go to 0".
AND mode need 32 channels all match trigger condition.
OR mode need one of 32 channels match trigger condition.
Event : allow trigger happen after match trigger condition max 1048576 times.
18
Delay : wait 1 to 1048576* (1 sec to 10nsec).
You can set the trigger logic to "Enter" (trigger when pattern matches) or "Exit"
(trigger when pattern stops matching).
Two trigger check be selected "trigger group" and serial trigger.
Trigger group check : Select which base you want to edit in.
Serial trigger : 7 kind of serial trigger can be selected as following:
Width Bit
Tradition logic analyzer only support 1 trigger level.
Advance logic analyzer can let this trigger word pass n time.
n =1 to 1048576.
In the following example, it will trigger if condition trigger word 55 happen 10 times.
like as 77,44,22,55,66,55,66,55,66,55,66,55,44,55,33,55,22,55,22,55,77,55 ← trigger here.
19
It also can set delay n time, n =1 to 1048576. time delay unit from 10nsec to 1 sec.
Some time we call this function as TRIGGER BEFORE DELAY.
It is useful when we need to look data after reset signal a long period.
In next diagram, it trigger after 10 times trigger word 55 with 10nsec*100 time delay
like as 77,44,22,55,66,55,66,55,66,55,66,55,44,55,33,55,22,55,22,55,77,55 -----1 μsec delay
← trigger here.
At this time all LA-2132 model can work well because it only use two trigger levels to complete.
LA-2132 has 2,8,512 trigger level model.
It need more than 2 trigger levels to complete next diagram example.
The following model can work for it
LA-2132-K8 (8 Trigger levels ), LA-2132-K512 ( 512 Trigger levels).
LA-2132-M8 (8 Trigger levels), LA-2132-M512 (512 Trigger levels).
LA-2132-G8 (8 Trigger levels), LA-2132-G512 (512 Trigger levels).
A serial of width bit stream like 33 follow 55 follow 77.
it will not trigger if data stream is 33,66,55,77.
20
21
The dead time of trigger level to next level is 7 clocks in 32 channels mode.
The dead time of trigger level to next level is 14 clocks in 16 channels mode.
The dead time of trigger level to next level is 28 clocks in 16 channels mode.
Width Bit With Timing
A serial of width bit stream like 33 follow 55 follow 77 by some timing .
It is 200nsec interval in this case.
Trigger commend wait 300nsec after detect trigger word 33 then check it in 200sec every time.
300nsec mean cross trigger word 33 200nsec plus trigger word 55 200nsec/2, equal 300nsec.
but system need 7 clock dead time to turn level to level, so it set 260nsec and 160nsec instead.
RS232 can be set in this mode, need set to 1 bit width.
The following model can work for it.
22
LA-2132-K8 (8 Trigger levels ), LA-2132-K512 (512 Trigger levels).
LA-2132-M8 (8 Trigger levels), LA-2132-M512 (512 Trigger levels).
LA-2132-G8 (8 Trigger levels), LA-2132-G512 (512 Trigger levels).
in this mode, also can detect width pulse in narrow stream.
It has width pulse 55 55 55 55 in the following stream.
like as .......... 55 aa 55 aa 55 55 55 55 aa 55 aa 55 aa 55..........
23
The same is true for detecting narrow pulse in width stream when set < nn time.
like 55 55 55 55 aa aa aa aa 55 55 55 55 aa aa aa aa 55 aa 55 aa 55 55 55 55 aa aa aa aa 55
55 55 55
All LA-2132 can work for it because it need two trigger level only.
But need adjust properly time delay.
Width Bit By Rising (Falling) Clock
A serial of width bit stream synchronous with clock. channel 31 default as clock.
channel 0-30 as data.
Data flow 77,00,55 synchronous with ch31 clock rising edge as following diagram.
Word 3 set to 1xxxxxxxxx.......
It detect data 77 after ch31 clock rising edge else go to trigger level 0 to judge continuously.
it also can select LSB out first or MSB out first
for example a stream 001111, LSB out first mean data flow is 111100.
MSB out first mean data flow is 001111.
24
25
The same is true for falling clock.
The following model can work for it
LA-2132-K8 ( 8 Trigger levels ), LA-2132-K512 ( 512 Trigger levels).
LA-2132-M8 (8 Trigger levels), LA-2132-M512 (512 Trigger levels).
LA-2132-G8 (8 Trigger levels), LA-2132-G512 (512 Trigger levels).
1 Bit Data By Rising Clock
A serial of bit stream synchronous with clock.
Channel 0 default as data, channel 1 default as clock.
It is same as "width bit by rising clock".
but it detect one bit only when clock is rising.
to avoid unnecessary start bit. leve0-2 let clock can work at first bit.
26
The same is true for falling clock.
The following model can work for it
LA-2132-K512 (512 Trigger levels).
LA-2132-M512 (512 Trigger levels).
LA-2132-G512 (512 Trigger levels).
I²C
It is same as "one bit by rising clock"
a serial of bit stream synchronous with clock. channel 0 default as data,
channel 1 default as clock in I²C format.
Level 0 -1 is I²C start format.
27
I²C need 73 trigger levels to complete trigger.
That is why LA-2132 need design 512 trigger levels.
The following model can work for it
LA-2132-K512 ( 512 Trigger levels).
LA-2132-M512 (512 Trigger levels).
LA-2132-G512 (512 Trigger levels).
Threshold Voltage Setup
it can set threshold voltage at toolbar or parameter form.
The range of threshold voltage is from -3.7V to 1.9V in 35mV step.
In general, 5V TTL need set 1.4V.
ECL (-1.3V)
LVC1.5V (0.75V)
LVC1.8V (0.9V)
LVC2.5V (1.2V)
LVC3.3V (1.4V)
SSTL2|| 2.5V (1.25V)
SSTL3|| 3.3V (1.4V)
Adjust threshold voltage can remove unnecessary signal like noise sometime.
LA-2164 support two sets threshold voltage.
Clock Menu
Select an internal clock rate or an external clock for sampling.
It can set clock rate at toolbar or parameter form.
1 GHz (1 ns) when select 8 channel mode only.
500 MHz (2 ns) when select 8 channel or 16 channel mode only.

At 16 channels mode.
External Clock
4 kind of external clock can be selected.
Channel 31 external clock rising.
Channel 31 external clock falling .
Channel 31 both of external clock rising and falling. it let external clock frequency double.
LVDS0 is external clock in LVDS signal.
The software only transfers data to the PC when the buffer is full. If you are using a
slow clock it might take a long time to fill the buffer. Recording time/Acquisition
time/Capture time/Buffer Length.
The Logic analyzer will acquire data for time equal to Buffer length * clock rate.
Example:
If buffer length = 512K and sample rate = 100KHz. The LA will record for (512K * 10 us)
Magnify (Timing)
Select a zoom ratio for the timing window. You can display the timing data in a compressed
or expanded format. Zooming in lets you see great detail. Zooming out lets you see large
abundant of data.
29
Zoom can be changed in the following ways:
1. A clicking on the combo brings up a magnify factor list.
2. Select what you want.
Zoom Combo
In the timing window you can do the following:
Zoom
Zoom in or out by selecting zoom factor combo
Window to cursor A :
Zoom around cursor A
Window to cursor B :
Zoom around cursor B
Window to cursor T :
Zoom around cursor T (trigger cursor)
cursor A to Window :
shift cursor A to window
cursor B to Window :
shift cursor B to window
cursor T to Window :
shift cursor T to window
cursor A, B, T to Window : shift cursor A, B, T to window
Timing Window
This window shows the data in a timing waveform style display. The channel names
will be on the left edge with the data going horizontally. To the right of the channel
names are the values of data at each cursor (it is color coded to match the cursors).
The vertical scrollbar moves the window up and down to display more channels. The
horizontal scrollbar moves the data forward and backward in time.
The channel order can be changed by the color form. The size of the window can be
changed by grabbing an edge of the window and dragging it.
30
When the Timing window is selected (title says "active window")
Left and right arrows scroll data with respect to time, or grabbing timing to shift data.
Up and down arrows scroll data with respect to channels.
Window to cursor A :
Window to cursor B :
Window to cursor T :
cursor A to Window :
cursor B to Window :
cursor T to Window :
cursor A, B, T to Window :
Zoom around cursor A
Zoom around cursor B
Zoom around cursor T ( trigger cursor)
shift cursor A to window
shift cursor B to window
shift cursor T to window
shift cursor A, B, T to window
Note:
This only works on the selected window.
Click on the window to select it.
Cursor using
Cursors are used to mark points of interest in the data, to measure time between events
and to define pre/post trigger position.
Moving a cursor:
1. In the timing you can select a cursor by using the arrow buttons in the timing move it.
2. You can also "grab" the cursor by left clicking on it in the timing and then move it by
"dragging" it to a new location.
3. The timing cursor A, B, T have selections that allow you to bring the cursors onto their
views.
31

Channel names should be edited at color form.
Color form also can set all cursor color.
Search By Cursor
Select one of cursor A, B, T and specific word.
or edit search word directly.
It will search all memory and channel after Push forward or backward.
34
Search By Group
The same is true for search by group after selecting search group check item.
It use group definition to quickly edit search word.
35

The following is source code of LA-2132 save and load data visual c program.
Sometime user want to analyze data by themselves. it is useful for user to understand how
program write and read data.
Every binary code describe 1 channel. For example 00110001 data mean channel 0 is high,
channel 1 is low...etc at first record.

Threshold Voltage Calibration
Let signal generator output a square wave from -5V to 5V.
Set threshold from -4.8 to 4.8V, it should get square waveform.
Set threshold to 5.2V, it should get low signal.
Set threshold to -4.8V, it should get high signal.
Trigger Word and Position Calibration
LA-55xx use software let trigger position always lock in 100% accuracy position, even you
zoom in the waveform, still lock in 100 % accuracy position.
Use LA-55160 arbitrary pattern generator to output some specific word like 01010101
00001111 10001101 1111111 00000000... etc.
then set trigger word. it should get trigger word at proper position.
54
it should test more than ten sets trigger word.
Trigger Sequential Calibration
Use LA-55160 arbitrary pattern generator to output some specific word like 01010101
00001111 10001101 1111111 00000000... etc.
then set trigger word from 1 to 15 sequential. it should get trigger word at proper position.
it should test more than ten sets trigger word.
Clock Source Calibration
It has two clock source, one is internal clock, another is external clock .
Use LA-55160 arbitrary pattern generator to output some 1/2 1/4 ... etc pattern .
the LA-55160 output sample rate is 1 to 100 MHz, for 1/2 pattern, it can get 1/2 Hz to 50
55
MHz square wave form. then set logic analyzer internal clock to proper sample rate to get
data, measure the data frequency should be 1/2 to 50 MHz. the same is true for external clock.
