Source 1:
Press the source 1 key to select any of CH1, CH2, CH3 or CH4 as source 1 of logic operations.
Source 2:
Press the source 2 key to select any of CH1, CH2, CH3 or CH4 as source 2 of logic operations.
Invert:
Press the invert key to select on or off. Select on to invert the waveform of the logic operation.
Threshold 1:
Press the PgDn key, and adjust the Multipurpose knob to change the value of Threshold 1. When the voltage value of the
source channel is greater than the value of Threshold 1, it is identified as logic “1”, otherwise it is logic “0”.
Threshold 2:
Press the PgDn key, and adjust the Multipurpose knob to change the value of Threshold 2. When the voltage value of the
source channel is greater than the value of Threshold 2, it is identified as logic “1”, otherwise it is logic “0”.
7.4 Digital Filter
Press MATH type , select digital filter to enter its menu.
Source:
Press the source button to select any of CH1, CH2, CH3 or CH4 as the source of digital filter.
Filter Type:
Press the filter type key to select low pass, high pass, band pass or band stop.
(1) Low pass: Only signals with the source frequency lower than the current frequency upper limit are allowed to pass.
(2) High pass: Only signals with the frequency higher than the current frequency lower limit are allowed to pass.
(3) Band pass: Only signals with the frequency higher than the current frequency lower limit and lower than the current
frequency upper limit are allowed to pass.
(4) Band stop: Only signals with the frequency lower than the current frequency lower limit or higher than the current
frequency upper limit are allowed to pass.
Frequency Lower Limit:
Adjust the Multipurpose knob to change the value of the frequency lower limit. When in low pass, the frequency lower limit
is invalid and the menu is hidden.
Frequency Upper Limit:
Adjust the Multipurpose knob to change the value of the frequency upper limit. When in high pass, the frequency upper
limit is invalid and the menu is hidden.
Note: The setting range of the frequency upper and lower limit is related to the current horizontal time base.
7.5 Advanced Operation
Press MATH type, select advanced operation to enter its menu.
Expression:
Press the expression key to select on or off. If you select on, it will pop up a Math-Advance dialog box, as shown below:
