Modifier name: MARKER
Modifier Syntax: MARKER hs numerical value [us state]
valid numerical values: 0 through 9, all
assumed units: no units (these are marker numbers)
State Syntax: ON, OFF, CLEAR
(turns marker on, off, or clears marker)
Modifier name: DEF_MKR
Modifier Syntax: DEF_MKR hs numerical value [us frequency f]
valid numerical values: 0 through 9
assumed units: no units
Frequency Syntax 1: FREQ hs frequency
(User defined marker frequency)
valid frequency values: 0 to 99999
assumed units: MHz
Frequency Syntax 2: CURSFREQ
(Assigns the current cursor frequency to the marker)
Modifier Examples: SWP 1;DEF_MKR 2;FREQ 3500
Defines Marker 2 on channel 1 at frequency 3500 MHz
SWP 4;DEF_MKR 9;CURSFREQ
Defines Marker 9 on channel 4 at the current cursor
frequency
SWP 2;MARKER 3;ON
Turn on Marker 3
SWP 1;MARKER ALL;OFF
Turn off all markers
SWP 3;MARKER 8;CLEAR
Clear marker 8 (turn off and clear frequency assign-

Modifier Description: These modifiers are used to perform an OPEN/SHORT
bridge calibration with trace memories instead of path
cal memories. The operator should connect a SHORT to
the bridge before the system executes the
STORE_SHORT modifier. The operator should then
connect the OPEN to the bridge and the system should
execute only the STORE_OPEN modifier by itself. The
SRQ service request is optionally used to tell the
controller when the analyzer has finished each
operation. Do not send the verb SWP n; before the
STORE_OPEN modifier (see examples next page).
