R&S ESU
Instrument Functions
Analyzer Mode
REF POINT
FREQUENCY
With the
REF POINT FREQUENCY
softkey a reference frequency can be manually
activated for the delta markers when the
REFERENCE FIXED
or
PHASE NOISE
function is used.
Remote command:
CALC:DELT2:FUNC:FIX:RPO:X 10.7MHz
REF POINT
TIME
The
REF POINT TIME
softkey activates the entry box for the input of a reference
time for the
REFERENCE FIXED
function in the time domain (span = 0 Hz).
Remote command:
CALC:DELT2:FUNC:FIX:RPO:X 5MS
For phase noise measurement, input of reference time is not possible.
PEAK SEARCH
The
PEAK SEARCH
softkey defines the maximum of the selected trace as refer-
ence level for all delta markers when using the
REFERENCE FIXED
function.
Remote command:
CALC:DELT2:FUNC:FIX:RPO:X -5DBM
Measurement example
Small-span harmonics measurement to increase sensitivity
CW signal (e.g. 100 MHz, 0 dBm) with harmonics at the RF input of R&S ESU.
MARKER
ZOOM
The
MARKER ZOOM
softkey expands the area around MARKER 1. With the zoom
function, more details of the spectrum can be seen. The desired display range can
be defined in an entry window.
The following sweep is stopped at the position of the reference marker. The fre-
quency of the signal is counted and the measured frequency becomes the new cen-
ter frequency. The zoomed display range is then configured and the new settings
are used by R&S ESU for further measurements.
As long as switching to the new frequency display range has not yet taken place,
pressing the softkey will abort the procedure.
[
PRESET
]
R&S ESU is set to the default setting.
[
CENTER
: 100
MHz
]
The center frequency of R&S ESU is set to 100 MHz.
[
SPAN
: 1
MHz
]
The span is set to 1 MHz.
[
AMPL
: 3
dBm
]
The reference level is set to 3 dBm (3 dB above the
expected RF level).
[
MKR
]
MARKER 1
is switched on ('1' highlighted in the softkey)
and set to the signal peak.
[
MARKER 2
]
MARKER 2
is switched on and automatically defined as the
delta marker (
DELTA
is highlighted on
MARKER NORM
DELTA
softkey).
[
REFERENCE FIXED
] The frequency and level of
MARKER 1
are a reference for
the delta marker.
[
CENTER
: 200
MHz
]
The center frequency is set to 200 MHz (= frequency of the
2nd harmonic). The reference level may have to be
reduced to see the 2nd harmonic from the noise. This does
not affect the reference level set with
REFERENCE FIXED
.
[
MKR->
:
PEAK
]
The delta marker jumps to the 2nd harmonic of the signal.
The level spacing of the harmonic to the fundamental is dis-
played in the marker info field.
