HP8340 emulation mode
AM value
Select amplitude modulation function, optionally set modulation depth.
Value:
value in PCT | %
Default:
0.0 PCT
Remark:
% is not supported.
AM must be preceeded by either S1, S2 or S3.
FM value
Select frequency modulation function. Optionally set modulation deviation.
Value:
value in HZ | KZ | MZ
Default:
0.0 HZ
Remark:
FM must be preceeded by either S1, S2 or S3.
S1
Select external modulation source.
Remark:
Coupling is AC in any case.
S2
Select internal 400 Hz sine wave as modulations source.
Remark:
Selection S2 sets LF frequency to 400 Hz for both, AM and FM. Any preceeding
selection of S3 is overridden.
S3
Select internal 1000 Hz sine wave as modulations source.
Remark:
Selection S3 sets LF frequency to 1000 Hz for both, AM and FM. Any preceeding
selection of S3 is overridden.
S4
Turn modulation completely or selectively off.
S5 value
Select DC frequency modulation function. Optionally set modulation deviation.
Value:
Value in HZ | KZ | MZ
Default:
0.0 HZ
Remark:
External modulation source is selected as well as DC coupling.
PM
Turn pulse modulation on.
