The measurement detector for the individual display modes can be selected directly
by the user.
The default setting is trace 1 in the overwrite mode ( CLEAR / WRITE) and detector
MAX PEAK is selected, trace 2 is also in the overwrite mode ( CLEAR / WRITE) and
detector AVERAGE is selected, trace 3 is switched off ( BLANK ).
The CLEAR/WRITE, MAX HOLD, MIN HOLD, AVERAGE, VIEW and BLANK soft-
keys are mutually exclusive selection keys.
SELECT
TRACE
The SELECT TRACE softkey activates the entry for the active trace (1, 2, 3).
Remote command:
-- (selected via numeric suffix of :
TRACe)
CLEAR/
WRITE
The CLEAR/WRITE softkey activates the overwrite mode for the collected mea-
sured values, i.e. the trace is overwritten by each sweep.
Each time the CLEAR/WRITE softkey is actuated, R&S ESU clears the selected
trace memory and starts the measurement anew.
Remote command:
DISP:WIND:TRAC:MODE WRIT
MAX HOLD
The MAX HOLD softkey activates the max peak detector.
R&S ESU saves the sweep result in the trace memory only if the new value is
greater than the previous one.
This is especially useful with modulated or impulsive signals. The signal spectrum is
filled up upon each scan until all signal components are detected in a kind of enve-
lope.
Pressing the MAX HOLD softkey again clears the trace memory and restarts the
max hold mode.
Remote command:
DISP:WIND:TRAC:MODE MAXH
VIEW
The VIEW softkey freezes the current contents of the trace memory and displays it.
If in the VIEW display mode the level display range ( GRID RANGE ) or the reference
level ( GRID MIN LEVEL ) are changed, R&S ESU automatically adapts the mea-
sured data to the changed display range. This allows an amplitude zoom to be made
after the measurement in order to show details of the trace.
Remote command:
DISP:WIND:TRAC:MODE VIEW
BLANK
The BLANK softkey activates the blanking of the trace on the screen.
Remote command:
DISP:WIND:TRAC OFF
SCAN
COUNT
The SCAN COUNT softkey activates the entry of the number of scan used in the
SINGLE SCAN mode.
The allowed range of values is 0 to 30000. The default setting is 1.
Remote command:
SWE:COUN 10
