CAUTION!
1. When the internal data is searched, the searched position may not be the same as the
display because the smoothing is performed to the internal data when SMOOTHING is
ON.
2.
∆
X and
∆
Y setting are possible only with ten keys.
Filter analysis menu
{WIDTH VALUE}
: Specifies the maximum loss when determining the
pass band. Specifies the loss (X dB) from the level
reference point.
{FILTER TYPE BAND/NOTC} : Selects the filter type.
BAND : Analyzes a band pass filter.
NOTC : Analyzes a notch filter.
{SEARCH FROM [ ]}
: To the search reference menu.
{DISPLAY MODE ABS/REL}
: Selects the way in which the bandwidth is displayed.
ABS
: Displays the bandwidth using two absolute
values ( i.e., the lower and higher
frequencies).
REL
: Displays the bandwidth relative to the
center frequency.
{SEARCH IN/OUT}
: Selects the direction to be searched on the stimulus
axis.
IN
: Searches outward from the search
reference point.
OUT
: Searches inward to the reference point.
{FILTER ANAL ON/OFF}
: Turns the measurement and its result display ON or
OFF. When ON, this function starts the
measurement and displays the result.
C.
F
: Displays the center frequency of the
bandwidth specified by the loss (X dB)
from the level reference point.
L.F
: In ABS mode, this displays the left
frequency of the bandwidth (the low
frequency pointed by the
↓
marker).
In REL mode, this displays the difference
between the left frequency of the
bandwidth and the center frequency.
R.F
: In ABS mode, this displays the right
frequency of the bandwidth (the high
frequency pointed by the
↑
marker).
In REL mode, this displays the difference
between the right frequency of the bandwidth
and the center frequency.
BW
: Bandwidth
Q
: Q factor
SF
: Shaping factor
Note:
When the format type is set except LOG MAG, MAG&PHASE/LOG, and
MAG&DELAY, if SMOOTHING is set to ON, a correct data cannot be searched.
