Key Reference
Meas
Rel Stop
Couple Man
Enters a relative level limit at
Stop Freq
ranging from –150.00
to +50.00 dBc with 4 significant digits, and to toggle this
function between
Couple
and
Man
. If set to
Couple
, this is
coupled to
Rel Start
to make a flat limit line. If set to
Man
,
Rel
Start
and
Rel Stop
the user can enter different values to make
a sloped limit line.

Fail Mask
Displays the menu to select one of the following logic keys
for fail conditions between the measurement results and the
test limits:
Absolute
,
Relative
,
Abs AND Rel
, and
Abs OR Rel
.
Key access:
Meas > SEM > Offset/Limits > More > More
Absolute
Sets the limit test to show Fail if one offset is
larger than the corresponding limit for
Abs Start
and/or
Abs Stop
. This is the default selection for
each offset for BTS measurements.
Relative
Sets the limit test to show Fail if one offsets
spectrum emission mask measurement results is
larger than the corresponding limit for
Rel Start
and/or
Rel Stop
.
Abs AND Rel
Set the limit test to show Fail if one offset’s
spectrum emission mask measurement results is
larger than both the corresponding limit for
Abs
Start
and
Abs Stop
and the limit for
Rel Start
and
Rel Stop
.
Abs OR Rel
Set the limit test to show Fail if one offset’s the
absolute spectrum emission mask measurement
results is larger than the corresponding limit for
Abs Start
and
Abs Stop
or the limit for
Rel Start
and
Rel Stop
.
Meas BW
Specifies the bandwidth to use when measuring the offset.
When using the front panel, only the currently selected offset
is affected. All the offsets are affected when remote control.
This is the multiplier applied to the resolution bandwidth to
determine the bandwidth to integrate when calculating the
power. Meas BW is restricted to be 1 and not changeable.
