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)
