PC-based logic analyser model La-Gold-16

Summary

A top-quality 16-channel PC-based logic analyser with pattern generator, the Janatek La-Gold-16 offers a comprehensive digital debugging environment for the electronics professional. It is similar to the La-Gold-36, but with 16 channels instead of 32.

It captures data at a maximum rate of 1GHz and has a buffer depth of up to 1 Meg samples per channel. It incorporates a pattern generator which can be used to stimulate the hardware being debugged whilst the logic analyser captures the response.

Benefits

The La-Gold-16 is a comprehensive 16 channel high specification logic analyser designed to speed debugging of digital electronic circuits. The very high sampling rate provides a more accurate representation of the signals on screen. (In general the sampling frequency should be 3 to 5 times faster than the shortest timing change being measured). 1 GHz provides 1 ns between samples.

The huge 1 Meg samples per channel buffer depth (up to 500 MHz sampling rate) allows longer captures without lowering the sampling frequency, thus maintaining sampling resolution. The combination of these two features on this analyser is difficult to beat, being especially useful for capturing high and relatively low frequency signals simultaneously.

Debugging is greatly aided by the integrated 8-bit pattern generator that can be used at the same time as the analyser is capturing data.

Software

The software for the La-Gold-16 is mature and both the logic analyser and pattern generator are controlled from a single, intuitive user interface. It is user friendly, and incorporates feedback suggestions from users.

The integrated pattern generator can be used in conjunction with the logic analyser. The user can set up the instrument under test (UUT) with the pattern generator and then measure its response with the logic analyser. This, and other flexible triggering options for both the logic analyser and pattern generator, make the La-Gold-16 a cut above the rest.

Capture the data that you want

The flexible triggering options make it possible to capture the exact data you want to view. Edge triggering may be set to occur on a rising edge, falling edge or change of state on any one or combination of channels.

Pattern (level) conditions are set by specifying a '1', '0' or 'X' (don't care) condition on all channels.

Combinations such as Edge OR Pattern, Edge AND Patter, Edge THEN Pattern, Pattern THEN Edge, may be set.

Pattern durations may be set to trigger when shorter (glitch capture), or longer than a specified period.

A 'post trigger delay' function allows the final data capture to be postponed by an accurate time after trigger detection

The integrated pattern generator

The pattern generator, working in close combination with the logic analyser, adds a new dimension to debugging possibilities.

The outputs of the pattern generator can act as inputs to the unit under test. The response from the unit under test can then be used to trigger the logic analyser.

The 8-channel pattern generator can output data at rates up to 50 MHz. The output patterns can be specified to come from a user file or from the 'Pattern Editor', seen opposite.

The pattern generator can be started on various conditions, for example, start on a specific condition in the logic analyser input signals, similar to a logic analyser trigger condition.

Detailed specification

(a) Acquisition system (hardware related)

Number of input channels	16 digital
Input voltage range (max)	-60 to + 60V
Impedance	1 Mohm, 5pF
Input bandwidth	100 MHz
Threshold voltage	-5V to +5V (variable for each group of 8 channels)
Data buffer	1 Meg samples per channel for 500MHz and below sampling 20k samples per channel minimum for 1GHz sampling
Pre/post-trigger buffer	The data buffer is divided into pre and post trigger sections. The pre/post buffer relation may be changed in 1000 samples steps
Internal sampling clock	Rates - 1GHz max. to 100Hz min. Stability - 100 ppm
External sampling clock	Synchronised capture: 50MHz max. Synchronised capture into linear/ring buffer Ring buffer configuration: Operates with pre and post trigger buffer Linear capture may start on trigger condition or immediately
Digital logger clock (Logging to hard disk)	Log rate - 1 second to 1 hour sampling rate
Post trigger delay (Extended capture time)	Depends on the sampling rate, at 500 MHZ - maximum delay = 33 ms at 1.25 kHz - maximum delay = 1677 sec
Instrument integration	Can combine with pattern generator functionality
Hardware self test	Comprehensive hardware self test facilities
Extension port	Useful signal inputs/outputs, e.g. output trigger to combine with external oscilloscope, pattern generator strobes, UART Tx/Tx busy, fifo empty/full etc

(b) Trigger conditions (configured using software)

Trigger Methods: Pattern
Pattern valid for any duration	"1", "0" and "don't care" ("X") conditions selectable on all channels

Triggers on:	Rising edge, falling edge, either rising or falling edge (change of state), of any one or combination of channels
Mouse/Keyboard	Trigger may be forced
Trigger Methods: Combination pattern/edge
Edge OR pattern	Edge or pattern condition that occurs first will cause a trigger
Edge AND pattern	For a trigger the edge condition must occur while the pattern condition is valid
Edge THEN pattern	The first condition is required before the second condition. At least 30ns is required from detection of the first condition to the second
Application of trigger conditions
Single capture	Captures a single set of data
Continuous capture display	Unconditionally continuous - trigger is forced internally and display updated at regular intervals. Conditionally continuous - display is updated when a trigger condition is detected. Any of the above trigger conditions may be set as described above. The display is updated on detection of a specified trigger condition
