HP 8510 back on.
3. The HP 8510 starts the error diagnostic routine. Press [

4. Run the main program by pressing [

Once the HP 8510 is sweeping, reset the phase lock by:
a.
Press [

} {
SYSTEM PHASELOCK
} {
NONE
}.
b.
Turn on the other instruments and reload the machine dump using
the correct MD_SYNWRxx file.
