Device:
Analogic 6100/6500 (3 in DEG)
Description: The Analogic is a high-accuracy, Universal Waveform Analyser. It is used in DEG for capturing transients / glitches at accuracy levels that the TDS digital scopes are not able to achieve. The captured data is usually uploaded to the SUN workstation for analysis, although the Analogic itself has many powerful analysis functions they are rarely used.
GPIB: The GPIB address is accessed by a number of DIP switches found at the back of the equipment.
General Info: The analogic has a +2.5v to û2.5v input range so all signals to be captured must be conditioned to be within these limits. A typical circuit used would contain two precision resistors acting as a potential divider and buffered through an AD845 (as shown in FIG 1).
Connection:
The analogic uses unique cables to connect to the Eval Board and hence a special PCB connector is needed. The PCB footprint (ANALOGIC_PROBE) for the connector generally used is shown in Fig2. This consists of the outer silver recepticle connected to ground and the gold inner signal connection. The input probe is usually connected to CHAN1. The TRIGGER input uses a BNC connector. The TRIGGER input is used to start the waveform capture.
Reset: The Analogic can be reset by simultaneously pressing the (BLUE) F button and the RST button.
The DIR and PROG button when pressed together will allow the user to put the device in Local or Remote mode to verify its operation manually.
Software: Practically ALL software needed to run the Analogic has been written already. Therefore all that is needed is to adjust the time period between samples, number of samples and the trigger delay. The best advice is to look at someone elses program and adapt it for you own needs.
