Amplitude
meas:refl:unit? Returns the reference level unit.
Parameter: 1 (dBm), 2 (dBmV), 3 (dBuV)
meas:refl:unit Sets the reference level unit. Parameter: 1 (dBm), 2 (dBmV), 3
(dBuV)Example: meas:refl:unit:_1 (dBm)
meas:refl? Returns the reference level in the current unit.
Example: −30 (−30dBm when the unit is dBm)
meas:refl Sets the reference level in the current unit.
Example: meas:refl:_−30 (−30dBm when in dBm)
meas:refl:scale? Returns the amplitude scale.
Parameter: 1(10dB/Div), 2(5dB/Div), 3(2dB/Div), 4(1dB/Div)
meas:refl:scale Sets the amplitude scale. Parameter: 1(10dB/Div), 2(5dB/Div),
3(2dB/Div), 4(1dB/Div) Example: meas:refl:scale_1 (10dB/Div)
meas:refl:exg? Returns the external gain/loss in dB. Example: −6 (−6dB)
meas:refl:exg Sets the external gain/loss. Example: meas:refl:exg_−6 (−6dB)
meas:refl:corr:edit Sets the amplitude correction data (frequency, amplitude). Need
to specify the table index and the number of correction.
Example: meas:refl:corr:edit_1_CR_2,100,−40,150,−30 (table
index1, 2 data, 100MHz/−40dB, 150MHz/−30dB)
meas:refl:corr:edit:
delall Deletes all point in an amplitude correction set. Need to specify
set index. Example: meas:refl:corr:edit:delall_5 (delete set No.5)
meas:refl:corr:on? Returns the activated amplitude correction set.
Parameter: none, 1 to 5 (correction set)
meas:refl:corr:on? Returns the amplitude correction set is active or inactive. Need
to specify the set index. Parameter: on, off
Example: meas:refl:corr:on_1? (set No.1 is activated?)
meas:refl:corr:on Activates the amplitude correction set. Specify the set index.
Example: meas:refl:corr:on_1 (activate set No.1)
meas:refl:corr:off Deactivates the amplitude correction set. Specify set index.
Example: meas:refl:corr:off_1 (deactivate set No.1)
meas:inputz? Returns the input impedance. Parameter: 0 (50 Ω), 1 (75 Ω)
meas:inputz Sets the input impedance. Parameter: 0 (50 Ω), 1 (75 Ω)
Example: meas:inputz_0 (50Ω)
meas:inputz:cal? Returns the input impedance calibration value in dB.
meas:inputz:cal
Sets the input impedance calibration value in dB.
Example: meas:inputz:cal_5.9 (5.9dB)
Autoset
meas:autoset:run Runs autoset.
meas:autoset:amp:auto Sets the autoset amplitude floor setting to auto mode.
meas:autoset:amp:man Sets the autoset amplitude floor setting to manual mode.
Need to specify the amplitude in dB.
Example: meas:autoset:amp:man_20 (20dB)
