AMPTD SF AN 30DB MAX
.E63
4063
An amplitude span of 30 dB is the maximum possible span. Either select an amplitude sweep setting
within the 30 dB span limitation or turn off the other amplitude sweep start or stop value (HP- IB: AAOF
or ABOF).
AP.SWP
LIMITS MIN TIME
.E64
4064
The minimum sweep time possible for amplitude sweep is 20 ms. Either select another sweep time or turn
off amplitude sweep (HP- IB: AAOF ABOF).
AP.SWP PREVENTS SP9
.E65
4065
Special Function 9 (Attenuator Range Hold) is not possible during amplitude sweep. Turn off amplitude
sweep (HP-IB: AAOF ABOF) and set amplitude (HP-IB: AP) before selecting attenuator range hold
(HP-IB: SP9).
SP9 PREVENTS AP.SWP
.E66
4066
Amplitude sweep is not possible when Special Function 9 (Attenuator Range Hold) IS selected. Select
Attenuator Range Hold Off (Special Function 209) before selecting amplitude sweep.
AM PREVENTS AP.SWP
.E68
4068
Amplitude sweep is not possible when AM IS selected. Turn off AM (HP-IB: AMOF) before selecting
amplitude sweep.
AP.SWP PREVENTS AMPTD
.E69
4069
Output amplitude cannot be set during amplitude sweep. Turn off amplitude sweep (HP-IB: AAOF
ABOF) before selecting the output amplitude .
AMPTD SWP PREVENTS AM
. E70
4070
AM is not possible during an amplitude sweep. Turn off amplitude sweep (HP-IB: AAOF ABOF) before
selecting AM.
AP.SWP
PREVENTS AP.OFF
.E71
4071
Output amplitude cannot be turned off during amplitude sweep. Turn off the amplitude sweep (HP-IB:
AAOF ABOF) before turning off the output amplitude .
AP.SWP
PREVENTS PULSE
. E72
4072
Pulse modulation is not possible during an amplitude sweep. Turn off the amplitude sweep (HP-IB: AAOF
ABOF) before selecting pulse modulation .
AP.SWP PREVENTS SP4
. E73
4073
Special Function 4 (ALC OFF) is not possible during amplitude sweep. Turn off amplitude sweep (HP -IB:
AAOF ABOF) before selecting ALC OFF (HP-IB SP4).
SP4 PREVENTS AP.SWP
.E74
4074
Amplitude sweep is not possible when Special Function 4 (ALC OFF) is selected. Select Disable ALe OFF
(Special Function 204) before selecting amplitude sweep .
SP9 LIMITS MIN AMPTD
. E75
4075
Special Function 9 (Attenuator Range Hold) limits the mInImUm amplitude that can be selected. To
resol ve
this problem, ei ther
1) select Attcnuator Range Hold Off (Special Function 209), or
2) select an amplitude within the held amplitude range selected, (refer to Table 3-1 5, page 3 -7 5, or
Figure 3 -- 9, page 3 -7 6), or
