Types of probes (continued)

Differential active probes (continued)

Active differential probe advantages Limitations

View small signals in the presence of DC • More expensive than general-purpose passive probes

or other common mode signals • Less dynamic range than using two passive probes

N2772A probes high-differential signals 20 MHz bandwidth

with low-thermal drift

1153A/1141A probes both low- and 200 MHz bandwidth

high-voltage differential signals with

low-thermal drift

1130A/31A/32A/34A and 1168A/69A Lower dynamic range and maximum input voltage (but has ultra low input

InfiniiMax probe probes both single-ended and capacitance)

differential signals up to 12 GHz bandwidth

1153A 200 MHz differential probe
