SEARCH MOD: BW
FULL Modifier Syntax: SCH[?] us BW hs numerical
value numerical value range: -90.00 to +90.00
numerical resolution: 0.01
assumed units: dBm, dB
query value returned: freq 1, freq 2, freq bw, data EOL
freq 1: lower frequency of bandwidth in MHZ. The format is
D.ddd where D is zero to six digits.
freq 2: upper frequency of bandwidth in MHZ. The format is
D.ddd where D is zero to six digits.
freq BW: bandwidth in MHZ. The format is D.ddd where D is zero
to six digits.
data:

.
ddd dB bandwidth (specified by host computer and
returned here for confirmation). Where D is zero to 3
digits to the left of the decimal point. The value is
returned to the host computer for confirmation.
SEARCH MOD: FLAT
FULL Modifier syntax: SCH? hs FLAT
query value returned: freq, data EOL
freq: freq = D.ddd where D is zero to 6 digits. The value
represents the current cursor frequency in MHz
data: Finds the curve flatness where flatness = maximum
trace power minus minimum trace power. Data format =
D where D is zero to three digits to the left of the decimal
point, and two digits to the right of the decimal point.
The assumed units are dBm or dB, depending on the
measurement mode.
This modifier defines the frequency of the cursor. The cursor will be placed at the
frequency specified by this modifier.
