Procedures
Cal Factor
0
If the frequency is correct but the cal factor is not, perform step 7
in the Entry Procedure for that frequency and enter its correct cal
factor only. (The HP 8901B
will
place the new entry in the correct
position in the table and remove the incorrect cal factor.) (For
example, if an incorrect cal factor value was entered for 10 MHz
you would correct it by entering
37.3 SPCL,
10
MHz,
the correct
cal factor value,
Blue Shift
key,
MHz.
The HP 8901B automatically
positions the new cal factor in the 10 MHz position in the table.)
Frequency
0
If an incorrect frequency is stored in the table, remove the
incorrect frequency by performing step 7 of the entry procedure
using the incorrect frequency and entering 0 as the cal factor.
Both
0
If you need to add both a frequency and its cal factor to the storage table,
perform the entry procedure (step
7)
for the correct frequency and cal factor.
(The HP 8901B
will
place the new entry in the correct position in the table.)
