Rate can be set from 1 to 10 bytes/sec. Use [
↑] and [↓] to select.
Accept value with [ENTER] and [EXIT] or cancel with [ESC].
[STEP] The Step Key, [STEP], is used to set the IEEE 488 bus handshake
speed to step or perform a bus handshake operation if the speed is
already set to step. The first press of [STEP] lights the SLOW LED
and sets the handshake circuitry to Slow operation. Subsequent
presses of [STEP] causes a single bus handshake to occur. [STEP]
enables STEP bus source or acceptor handshaking. Source (Talk) or
acceptor (Listen) handshaking is dependent on -SOURCE- keys.
Subsequent [STEP] or [ENTER] key presses initiates (Talk state)
or completes (Listen state) one handshake sequence if in bus display
mode.
STEP LED The STEP LED indicates that the IEEE 488 bus handshake speed is
currently set to single step operation to record and/or view bus
events individually in a single-step fashion. [STEP] must be
pressed to complete each event. Changing the handshake speed may
be accomplished using the [FAST], [SLOW], or [NONE] keys.
[NONE] The None handshake key, [SHIFT][STEP], disables the
Analyzer488 from handshaking on the IEEE 488 bus. Pressing
[NONE] disables handshaking and displays a status message:
