User Manual

 When the coupling is set to DC, both the DC and AC components of the signal will be

displayed.

 When the coupling is set to AC, the DC offset of the signal is blocked.

 When the coupling is set to GND, both the DC offset and AC components of the signal are

both blocked.

Press the 1 button on the front panel, then press the Coupling softkey and turn the Universal

Knob to select the desired coupling mode. The default coupling is DC.

The current coupling mode is displayed in the channel label at the right side of the screen. You

can also press the Coupling softkey repeatedly to switch between the coupling modes.

Specify Bandwidth Limit

Set the bandwidth limit to reduce displayed noise. For example, the input signal is a pulse with

high frequency oscillations.

 When the bandwidth limit is set to none, the high frequency components of the signal under

test can pass the channel.

 When the bandwidth limit is set to 20MHz, the high frequency components above 20 MHz

are attenuated.

Press the 1 button on the front panel, then press the BW Limit softkey to select none or 20M.

The default setting is none. When the bandwidth limit is enabled, the character B will be

displayed in the channel label at the right side of the screen.

Specify Probe Attenuation Factor

Set the channel's attenuation factor to match the attenuation of the probe you are using to

ensure correct voltage or current measurements. To do this, press the 1 button on the front

panel, then press the Probe softkey and turn the Universal Knob to select the desired

attenuation. Push the knob to select the chosen value. The default is 1X. You can also press the

Probe softkey repeatedly to change the channel's probe attenuation factor.

Specify Channel Input Impedance

Select the channel input impedance: 1 MΩ and 50 Ω. Do not exceed a voltage input of more than

5 V absolute value for a 50 Ω impedance input or 400 V absolute value for a 1 MΩ impedance

input. A high impedance of 1 MΩ minimizes loading the device under test.

Press the channel button on the front panel, then press the Impedance softkey to toggle between

1 MΩ and 50 Ω. The default is 1 MΩ. The channel's input impedance is displayed in the channel

label at the right side of the screen.
