Janatek Annie-USB 8-Channel Logic Analyser
Janatek Annie-USB 8-Channel Logic Analyser
Overview
The Janatek Annie-USB is an 8-Channel logic analyser with an integrated pattern generator that gives you the functionality and quality of an expensive logic analyser at the price of an inexpensive one.
The Annie-USB has a maximum sampling rate of 500MHz and a buffer depth of 1Msamples per channel.
Note: The supplied software is compatible with Windows 98, ME, 2000 and XP.
The Annie-USB is an 8-channel PC-based logic analyser with probably the highest specifications in its class. It can capture data at a maximum rate of 500MHz and has a buffer depth of up to 1 Mega-samples per channel. The Annie-USB can also be used as an 8-channel digital pattern generator!.
Summary |
A top-quality 8-channel PC-based logic analyser with probably the highest specifications in its class, this Janatek product is excellent value for money.
It captures data at a maximum rate of 500MHz, has a buffer depth of up to 1 Meg samples per channel, and incorporates an 8-bit pattern generator to aid debugging.

Benefits |
The high sampling rate available on this analyser 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). 500 MHz provides 2 ns between samples.
The huge 1 Meg samples per channel buffer depth 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.

Software |
The software for the analyser is intuitive, very easy to understand and gives the user one-button access to most of the Annie-USB's advanced features. It is user friendly, and incorporates feedback suggestions from users. You could be taking meaningful measurements minutes after installing it for the first time.
The Annie-USB interfaces to the PC via the USB port. It utilizes USB-2 in its highest speed mode, but is also compatible with USB-1.1. No external power supply is required.
The Annie-USB offers high performance, excellent value for money and ease-of-use.

Data buffer size: | 1 Meg samples per channel |
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: 500, 200, 100, 50, 25, 10, 5, 2.5, 1 kHz: 500, 250, 100, 50, 25, 10, 5, 2.5, 1.25 Stability - 100 ppm |
External sampling clock | Input to channel 7 Asynchronous - clock on rising/falling edge, 25MHz maximum synchronous - clock on rising/falling edge, 10MHz maximum |
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: 500 MHZ - maximum delay = 131 μs 200 MHz - maximum delay = 10 ms 1 MHz - maximum delay = 16 sec 2.5 kHz - maximum delay = 6710 sec Accuracy - 5 x sampling period |
(b) Trigger conditions (configured using software)
Pattern | "1", "0" and "don't care" ("X") conditions selectable on all channels |
Edge | Rising edge, falling edge, either (change of state), on any channel. |
Edge/Pattern combinations | Edge OR pattern (whichever 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 / Pattern THEN edge (the first condition is required before the second condition |
Continuous | Unconditionally - display updated at regular intervals. Conditionally - display updated when a trigger condition is detected. Any of the above trigger conditions may be set as described above. |
Pattern valid for more or less than a specified time | trigger if pattern < duration (glitch capture), duration ±20ns tolerance, 1 ms max trigger if pattern > duration, duration ±20ns tolerance, 1 ms max |
Mouse/Keyboard | A trigger may be forced |
