PC-based logic analyser model La-Gold-36

Summary

A top-quality 32-channel PC-based logic analyser with pattern generator, the Janatek La-Gold-36 offers a comprehensive digital debugging environment for the electronics professional.

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-36 is a comprehensive 32 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-36 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-36 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 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 50MHz. 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.

Data buffer size:	1 Meg samples per channels up to 500MHz 4k samples per channel minimum at 1GHz sampling rate (dependent on number of channels used)
Pre/post-trigger buffer	The data buffer is divided into pre and post trigger sections. Sizes can be changed in 1000 samples steps
Internal sampling clock	Rates - MHz: 1000, 500, 200, 100, 50, 25, 10, 5, 2.5, 1 kHz: 500, 250, 100, 50, 25, 10, 5, 2.5, 1 Hz: 500, 250, 100 Stability - 100 ppm
External sampling clock	Input to channel 31 Asynchronous (linear on trigger or immediately) - clock on rising/falling edge, 50MHz maximum, (data valid 10ns before clock edge) synchronous (into linear/ring buffer) - clock on rising/falling edge, 50MHz maximum, (data valid 10ns before clock edge)
Digital logger clock (Logging to hard disk)	Log rate - 1 second to 1 hour in 1 second steps Stability - logger timing obtained from PC
Post trigger delay (Extended capture time)	Depends on sample frequency: 1 GHZ - maximum delay = 65μs 500 MHZ - maximum delay = 33 ms 200 MHz - maximum delay = 83 ms 1 MHz - maximum delay = 16 sec 2.5 kHz - maximum delay = 6710 sec Accuracy - 5 x sampling period
