Key Reference
Meas
128
Start Freq
On Off
Specifies the inner limit (frequency closest to the carrier) for
both segments of the specified offset pair. When
Start Freq
(Off)
is selected, the offset pair is not measured.
Key access:
Meas > SEM > Offset/Limits
Stop Freq
Specifies the outer limit (frequency furthest from the carrier)
for both segments of the specified offset pair. The minimum
frequency difference between
Start Freq
and
Stop Freq
is limited
to 100 Hz.
Key access:
Meas > SEM > Offset/Limits
Sweep Time
Auto Man
Specifies the sweep time for the currently selected offset, and
toggles this function between
Auto
and
Manual
for each offset.
Key access:
Meas > SEM > Offset/Limits
Res BW
Auto Man
Specifies the resolution bandwidth used in measuring the
offset pair. When set to
Auto
, the Res BW are used. When set
to
Man
, the allowed range is 1 kHz to 1MHz.
Key access:
Meas > SEM > Offset/Limits
Abs Start
To enter an absolute level limit at
Start Freq
for the currently
selected offset ranging from –200.00 to +50.00 dBm with 4
significant digits.
Key access:
Meas > SEM > Offset/Limits > More
Abs Stop
Couple Man
To enter an absolute level limit at
Stop Freq
for the currently
selected offset ranging from –200.00 to +50.00 dBm with 4
significant digits, and to toggle this function between
Couple
and
Man
. If set to
Couple
, this is coupled to
Abs Start
to make
a flat limit line. If set to
Man
,
Abs Start
and
Abs Stop
the user
can enter different values to make a sloped limit line.
Key access:
Meas > SEM > Offset/Limits > More
Rel Start
Enters a relative level limit at
Start Freq
ranging from –150.00
to +50.00 dBc with 4 significant digits.
