7. High Frequency Rejection
High frequency rejection can be used to filter out the high-frequency
components and improve the measurement accuracy in low-frequency signal
measurement. Tap the High Freq Rejection parameter selection field to
enable or disable the high frequency rejection function.
Note: Enable the high frequency rejection when low-frequency signal with less
than 200 kHz frequency is measured to filter out the high-frequency noise
interference. Disable the high frequency rejection when high-frequency signal
with greater than 200 kHz frequency is measured. At this time, the maximum
input frequency can be 240 MHz.
