MEASurement<m>:GATE:RELative:STARt <Position>
MEASurement<m>:GATE:RELative:STOP <Position>
Define the relative start and end values for the measurement gate, respectively.
Suffix:
<m>
.
1..4
The suffix is irrelevant. One gate is used for all measurement
places.

REFLevel:RELative:MODE <RelativeMode>
Sets the lower and upper reference levels for rise and fall time mesurements (cursor
and automatic mesurements) as well as the middle reference level for phase and delay
measurements. The levels are defined as percentages of the high signal level. The set-
ting is valid for all measurement places.
Parameter:
<RelativeMode> TEN | TWENty | FIVE | USER
TEN: 10, 50 and 90%
TWENty: 20, 50 and 80%
FIVE: 5, 50 and 95 %
USER: levels are defined with REFLevel:RELative:LOWer,
REFLevel:RELative:MIDDle and REFLevel:RELative:
UPPer.
*RST: TEN
Beispiel:
REFL:REL:MODE TWENty
MEAS2:MAIN RTIM
Sets the reference levels for all measurements and measures
the rise time between these levels for measurement place 2:
lower reference level = 20% of high signal level
upper reference level = 80% of high signal level
