Probe Field; Coupling Field - HP 16534A User Reference

Probe Field

You use the Probe field to set the probe attenuation factor for the input
channel currently displayed in the Input field.
Probe Attenuation Factor
The probe attenuation factor can be set from 1:1 to 1000:1 in increments of
one. When you select the Probe field, the probe attenuation factor can be
changed by turning the knob or by entering a value from the pop-up keypad.
When you select a probe attenuation factor, the actual sensitivity at the input
does not change. The voltage values shown on the display (V/div, offset,
trigger level) are automatically adjusted to reflect the attenuation factor.
The marker and automatic measurement voltage values change when Run is
touched and the next acquisition is displayed
The default value for the Probe field is 10:1 for 10:1 divider probes.

Coupling Field

You use the Coupling field to set the input impedance for the channel
currently displayed in the Input field.
Coupling Field Selections
When you touch the Coupling field, a pop-up appears that shows the input
impedance values available for selection. The selectable values are as
follows:
•
1MΩ / DC
•
1MΩ / AC
•
50Ω / DC.
The default value for the Coupling field is 1MΩ / DC.
The maximum input voltage for the 50Ω / DC Coupling field selection is 5
