PC-based logic analyser model Annie-USB

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.

    It is better to buy a logic analyser with a few good channels than one with many poor channels.

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.

Detailed specification

(aAcquisition system (hardware related)

Number of input channels 8 digital
Voltage range 0 to 7 V
Impedance 1 Mohm 1%, 8pF
Bandwidth 50 MHz minimum
Threshold voltage 1.2 - 2.3 V
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

(c)  Pattern generator

Pattern source

Pattern editor or user file
Number of channels 8
Data output clock rate 20 MHz maximum
Minimum input impedance of load 4k7 / 100pF
Modes of operation Single/continuous
Note: the Annie-USB can only act as a pattern generator OR analyser, not both at the same time. For simultaneous operation, see the La-Gold-36
