Threshold voltage: 1.2V to 2.3V
Digital inputs

 

Input voltage: 0 – 7V
Input bandwidth: 50MHz min
Input impedance: 1M ±1% minimum , 8pF
Trigger methods:  
Pattern :

(Pattern valid for any duration )

1, 0, and "don't care" ("X") conditions selectable on all channels.  The pattern must be valid for at least 20ns.
Pattern valid < Duration Glitch  Capture. Pattern duration  may be specified in steps of 20ns to 1 ms. Duration tolerance of ±20ns
Pattern valid > Duration Pattern duration may be specified in steps of 20ns to 1 ms. Duration tolerance of ±20ns
Edge : Triggers on: Rising edge, falling edge, either rising or falling edge (change of state ), of any one channel
Mouse /Keyboard Trigger may be forced.
Edge/Pattern combinations : Edge : Rising edge, falling edge, Change of state

Pattern : 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.  The pattern must be valid for at least 20ns before the edge and 20ns after the edge.

Edge THEN Pattern  / Pattern THEN Edge: The first condition is required before the second condition.  At least 30ns is required from detection of the first condition to the second.

Continuous : Unconditionally Continuous : Trigger forced internally and display updated with regular intervals.

Conditionally Continuous : Display updated when a trigger  condition is detected.  Any of the above trigger conditions may be set as described above.

Pre-trigger  and post-trigger  buffer setting: The data buffer  is divided in pre- and post trigger  sections.  The pre-/post-trigger buffer relation may be changed in 1000 samples steps.
Software environment  
Windows: Windows 98, ME, 2000, XP, Vista, Win7 or later compatible versions.

The power of the Windows multitasking environment is utilised to run the analyzer software and user’s unit under test  (UUT ) software simultaneously (if the UUT is PC based).

Hardware that interfaces with the PC may be driven from the PC while real-time measurements are performed on the hardware.  (The logic analyzer and UUT  software are simultaneously run on the same PC).  The analyzer and the user program may be viewed simultaneously in the Windows environment.

Ease of use: The software is very easy to use.  Most functions are directly selectable by means of function buttons on the main screen.
User UUT application program launching: The user application program may be run from the analyzer program menu or from Windows.
Display :  
No. of  channels: Any number of channels may be displayed.
Channel/group names User specified signal names
Display order : Channel display order user specified
Colors Specify colors for individual signals, background.
Zooming: Data zoom :

All captured data may be viewed on one screen. Zooming in to only a few samples displayed on the screen

Easy data display window sizing using the mouse.

Single capture Captures a single set of data

Continuous capture display:

 

Unconditionally:  Continuously captures and displays data at a fixed update period.

Conditionally:  Updates the display each time a specified edge or pattern trigger  condition is met.

Cursors : T-trigger  line: Indicates trigger position.

P-trigger line : Indicates trigger condition-1 position in case of condition-1 THEN condition-2  setting. S-Cursor line indicates data search positions. X, Y and Z-cursor for time measurements.

The values of the X and Y cursor lines, where they intersect the signal lines are shown.

Time measurements : The time differences between any two cursor lines or trigger  line may be displayed. Take measurement easily by clicking mouse on first edge and on second edge to get the time difference. The time difference may also be indicated as a frequency.
Edge snapping : Cursors (X, Y & Z) snap to signal edges for accurate time measurements.  (Especially useful when the display is zoomed out so that one screen pixel represents more than one data sample).

The signal edges to which the cursors lines have been snapped are indicated

Pattern search : Any channel conditions may be searched for.  1, 0 and don't care conditions specified.

Also repeated search

Printed output : The timing diagrams, bitmaps, binary and hex data, may be.  Landscape and portrait.
Power requirements:

2.5W Max (Capturing data)

The Annie-USB will be fused with a 1.6A (or less)

Resetable fuse. Remove power for 3 minutes to reset.

Internal sampling clock stability 100 PPM
External clock Input to channel 7.

Unsynchronised capture: 25Mhz Max Synchronised capture: 10 MHz Max, 30ns data valid on channel 0-6 before and after the clock signal on channel 7 changes. Ring buffer  configuration: Operates with pre and post trigger buffer.

Linear buffer  configuration: Start capture immediate or from trigger. No initial clock pulses are missed with either immediate or from trigger capture.

Logger sampling clock Timing obtained from PC
Cursor to T-line accuracy T-Line onscreen: ± 1 sampling clock  period (1.25 kHz to 500/200 MHz)
