Appendix F Frequency Lists
F.1 IEC Third Octave Frequencies (and remote codes)
Table F.1 shows the nominal third octave frequencies which are used by the LA101 in
manual mode when the frequency is changed with the
keys. These
frequencies are also used for third octave frequency sweeps and the code refers to the
third octave frequency code which is used from remote mode when running third octave
sweeps with the
TS command. Frequency code Frequency list Synthesised frequency Third octave frequencies IEC third octave frequency
The actual frequencies which the LA101 generates are shown below in table. F.2.

F.2 LA101 Frequencies and Remote Codes
The actual frequencies which can be synthesised by the LA101 oscillator are shown
below in fig. F.2. These frequencies will be displayed in manual mode after a fine
frequency change is made by pressing
or . When using the normal third
octave frequency buttons
and the displayed frequency is normally rounded to
the nearest third octave. The LA101 can be forced to always display the true frequency
which is being generated by setting configuration F2. See section 2.2.
The code listed beside each frequency is the frequency code which should be used in the
remote
F: and SW commands. See sections 9.9 & 9.11.
