Section 5 Analyst488 Software

5.22

5.11.4 Slow

This command configures the Analyzer488 handshake circuitry to

perform a handshake at a slow rate of 1 to 10 events per second. When

this command is issued, a menu will appear showing the valid speed

selections.

5.11.5 Step

This command configures the handshake circuitry to perform one

handshake each time the Step command is issued. When the command is

first issued, the handshake speed is set to Step and 1 handshake is

performed. In this way, each bus events may be easily viewed. If you are

using handshake Step speed, the Step command must be used to complete

each bus event whether talking or listening on the bus.

This command may also be selected without pulling down the

Handshake menu by pressing

<F10>

. Each step is also performed by

pressing

<F10>

5.11.6 None

This command disables the handshake circuitry and allows the

Analyzer488 to record bus data without appearing to be an active listener.

The Analyzer488 does not participate in bus handshaking and has no

control of the bus event speed. This selection is useful for recording events

such as bus errors and measuring the speed of other devices on the bus. It

also shows such errors as no active listeners.
