MKBW Marker Bandwidth
MKBW
Marker Bandwidth
Returns the bandwidth at the specified power level relative to an on-screen marker (if present)
or the signal peak (if no on-screen marker is present).
Syntax
Pre’def i ned
function path only
Item Description/Default Range
Number Any valid negative integer. 0 to the amplitude of
the noise floor.
Example
OUTPUT 718. “IP * ”
OUTPUT 718;"CF'SOOMHZ;SP 1OOMHZ;SNGLS;"
Initializes spectrum anulyzex
Changes the center j?-equency and span,
then activates the single-sweep moo%.
OUTPUT 7 18 ; “TS ; MKPK HI ; ”
Updates the sweep, places marker on signal
peak.
OUTPUT 718 ; “MKBW -3 ; ”
Uses the MKBWjimction to find the signal
bandwidth at -3 dB below the marker:
Description
The MKBW command also displays (in the message area) the bandwidth at the power level in
dB below the current marker position or the current signal peak.
MKBW finds the bandwidth at the specified power level for one measurement sweep. If you
want the spectrum analyzer to find the bandwidth at the specified power level during every
measurement sweep, use the NDBPNT command instead of MKBW.
