N2820A Probes and Dual-Grid View
When using an N2820A probe on a 9000 H- Series or 9000A
Infiniium oscilloscope, the zoomed- in and zoomed- out
waveforms can be simultaneously viewed in dual- grid view,
as shown in Figure 9. In dual-grid view, the zoomed-out
waveform originates from the probe's low- gain amplifier, and
the zoomed- in waveform originates from the probe's
high- gain amplifier. The zoomed- in waveform has less noise
and dynamic range than the zoomed- out waveform.
NOTE Dual-Grid View is not supported in InfiniiVision oscilloscopes.
