Adjustment Procedures
TDS3000 Series Service Manual 5–3
Signal ConnectionsThe adjustment procedure requires three types of equipment setups if you are
adjusting a four-channel oscilloscope, or four types if you are adjusting a
two-channel oscilloscope. For each step of the procedure, the oscilloscope
display indicates which setup is the correct one to use. The equipment setups are
described below.
The first steps require a DC voltage (or zero volts) to be applied simultaneously
to all the channels. A typical on-screen instruction might read:
When you see an instruction similar to this, connect the oscilloscope to the DC
voltage source to all the channels as shown below and then set the DC voltage to
the specified value.
