Utility Function 70
13.17 High Frequency Rejection
High Frequency Rejection can be used to lter out the high-frequency components of a measured signal and improve the
measurement accuracy in low-frequency signal measurement. Press HFR to enable or disable this function. The default
is “O”.
• Enable High Frequency Rejection when low-frequency signal with lower than a 250kHz frequency is measured to lter
out the high-frequency noise interference.
• Disable High Frequency Rejection when a signal with a frequency higher than 250 KHz is measured. The maximum
frequency that can be counted is 200 MHz.
13.18 Output
Press Utility → Output to enter the following interface.
Figure 13.13 Output Setup Interface
13.19 Load
For the [CH1] and [CH2] connectors on the front panel, the generator has an output impedance of 50Ω. If the actual
load does not match the set load, the displayed voltage will not be the same as the output voltage. This function is used
to match the displayed voltage with the expected one. This setting does not actually change the output impedance to
any other value.
13.19.1 Steps for setting the load:
Press Utility → Output Setup → Load, to set the output load. The load parameter shown on the down bottom is the
default setting when the power is on or the pre-set load value.
High Impedance: displayed as HiZ;
Load: the default is 50Ωand the range is 50Ωto 100kΩ.
Note: Continue pressing the corresponding output key for two seconds to switch between High Impedance and 50Ω.
13.20 Polarity
Press Utility → Output Setup → Polarity to set the output signal as normal or inverted. The waveform’s inversion is
relative to the oset voltage, as shown in the following gure.
