Additional Functions
Line monitor function
The states of all control lines (IFC, ATN, SRQ, REN, EOI, DAV, NRFD, and NDAC) can be read. The
latch data can also be read. You can also read the current state of the data lines (DIO1 to DIO8).
Communication using FIFO memory
The PC card can use on-board FIFO memory for communication. As the PC card controls this form of
communication, it can be performed at high speed irrelevant to the PC’s CPU speed.
Note, however, that the actual communication speed is set to the speed of the slowest device in
compliance with the GPIB standard.
Analyzer function (GP-IB(CB)F)
The state transition of all lines in the GPIB cable can be analyzed by using the on-PC Card FIFO
memory. (A maximum of 64K data items can be collected.)
This function can be used to locate the cause of a failure or to check data flowing on lines.
The function is provided by the analyzer utility (Analyzer.exe).
Open the Start Menu, then select “CONTEC API-PAC(W32)” – “GPIB” – “GPIB ANALYZER”.
Otherwise, directly execute “Program Files\API-PAC(W32)\GPIB\ANALYZER\Analyzer.exe”.
Running Method
(1) Install the PC card on your PC according to Step 2 “Setting the Hardware” and Step 3 “Installing the
Hardware” in Chapter 2 “Setup”.
After having installed the PC card, connect the PC Card to an instrument for analysis. The PC card
can communicate with the instrument while executing analysis.
