Compatible Oscilloscopes
S series, 90000 V, X, Z, and Q series (with N5442A Adapter), 90000A series, 86100D (with N1022B A dapter), and
80000B series
To connect the probe to the oscilloscope
1. With the lever in relaxed position push the probe onto the BNC.
2. The lever moves towards the R (release) and returns to symbol.
3. Move the lever towards the symbol until snug.
To disconnect the probe from the oscilloscope
To disconnect, move and hold the lever at R (release) and pull the probe from the BNC.
