Nonvolatile Clear or
Sanitize Procedures
Check 80Cxx Modules User Wavelengths and Scales.
Use the following procedure
to check if the 80Cxx module User Wavelength(s) and Scale(s) are set to the
factory defaults and to record information for later recovery.
1. Power down the instrument and insert the optical module into the upper left
large slot. Note: the upper right large slot may also be used, adjusting the
channel parameter to CH3.
2. Power up the instrument and wait for the oscilloscope application to become
active.
3. From Table 3 for the applicable module(s), send each of the programmable
interface query commands to the instrument. Note that the 80C10 contains
two pairs of wavelengths and scales.
4. If the user wavelength(s) and user scale(s) returned match the factory default
User Wavelength(s) or User Wavelength Scale(s), no further sanitize actions
are necessary.
5. If either the user wavelength(s) or user scale(s) returned do not match the
factory default User Wavelength(s) or User Wavelength Scale(s), sanitizing
is necessary.
For recovery at a later time, fi rst write down the User Wavelength(s) and
User Wavelength Scale(s), and store in a secure location.
Perform the procedure Sanitize 80Cxx Module to Factory Default Settings
for User Wavelength(s) and Scale(s) .
