Figure 3-9 External Clock dialog box
Item
Description
Speed(Sample
rate)
Also called asynchronous acquisition, the input signals are sampled
and stored at equal time intervals based on LAP Educator’s internal
clock. The sample rate determines how often samples are taken. The
Timing mode sample rate goes from 100Hz to 100MHz.
External Clock
Also called synchronous acquisition, the clock that governs when to
sample data is provided by the DUT. External Clock provides a view
of how the system is executing. One sample is taken per clock cycle
and the user must specify whether he wants to sample on rising or
falling DUT clocks, or on either. The External sample rate goes from
0.001 Hz to 75MHz.
Memory
Determine the amount of data to be acquired per channel; it is set to
2 k by default.
Total Time
The total time of acquiring data depend on Sample rate and Memory.
Trigger Level
The Trigger Level defines when a signal changes state. In other
words; if the voltage of a signal is inferior to the Trigger Level it will
be regarded as 0 (Low), and vice versa. That is set -6V to +6V.
Trigger Position
The trigger position determines which samples are stored. At the
default 10%, 10% of the available memory is allocated to pre-trigger
Page 42
LAP Educator Logic Analyzer | User Guide v1.00.01 |www.zeroplus.com.tw
42
data and 90% to post-trigger data.
Compression
The Compression function can be used to extend the length of
acquisitions. The principle goes as follows: Rather than storing 100
consecutive 1s, the LAP Educator stores 1x100 using the hardware
based algorithm. The function is therefore most efficient when
sampling buses that are idle for significant amounts of time, when a
maximum compression rate of 255 can be reached. In other words, 1
Mb of memory can be used to acquire up to 255 Mb of data. Note
that the function is disabled by default as a negative compression
rate is possible for signals with high variability. Note that no data
will be lost when using Compression.

Chip Select Settings
(Channel and
Level)
The Chip Select function emulates a real chip select. The function is
similar to the Latch function (below) in that it decodes bus data, but it
only does so when all the conditions are met.
Latch Setting
(Channel and
Event)
The Latch function is used to analyze/decode bus activity that does not
use a specific protocol (referred to simply as a Bus in ZP-Studio). When
selecting a channel and an event (for instance A0 and Falling Edge), the
bus data will be decoded and displayed at every occurrence of this
event.

The Image Encode function is specially designed for display type protocols such as
I2S, LCD1602 etc. Captured data that are decoded with one of the supported
protocols are decoded and displayed as the original picture. This makes for a painless
and straightforward verification of the data being correct or not. See Figure 3- for an
example of the function’s output.

The Navigator is a condensed form of the main waveform that is always zoomed to
fit the entire capture of the pages in focus. It facilitates waveform navigation by
providing an overview of the entire acquisition and a tool for quick movement
between distant parts of the acquisition. The Navigator is synchronized with the main
waveform so users can shift the waveform focus from one part of the acquisition to
another simply by clicking in the Navigator.
A light blue frame (in the left part of Figure 3-) in the Navigator indicates which part
of the waveform that is in focus; this frame naturally changes size when zooming as
it is inverse proportional to the zoom rate. Four signals are shown at a time; scroll up
or down to focus on other channels.
The Navigator is show by default under the waveform area in the Secondary Display
