SWEEP TIME ADJUSTED .e2l
2021
Sweep time was adjusted to the l111nimum allowed setting. The sweep time setting was less than the
minimum allowed for the type of sweep selected. Either a Stepped Frequency Sweep was set with the
sweep time set less than 275 ms, or amplit ude sweep was set with the sweep time set less than 20 ms.
FREQ SWEEP TURNED OFF .C22 2022
RF frequency sweep was turned off. Either (FREQ I, [START AMPTD I, or I STOP AMPTD 1 was
selected (HP-IB codes: FR, AA, AB) when RF frequency sweep was on.
FR.SWP+AM TURNED OFF .C23
RF frequency sweep and AM were turned off. Either CSiARlAJv1PTPl
selected (HP-IB codes: AA, AB) when RF frequency sweep was on with AM .
AMPTD SWP TURNED OFF . C3l

or (STOP AMPTID was
2031
Amplitude sweep was turned off. One of the following functions was selected when amplitude sweep was
on: ( START FREQ I, ( STOP FREQ J, ( AMPTD J,~, or PULSE ( ( SHIFT J C8J2!J).
(HP-IB codes: FA, FB, AP, AM, PL).
AA.OFF ... 30DB MAX SPAN .C32
2032
Start amplitude setting was turned off because the new stop amplitude setting was set more than 30 dB
away from the start amplitude setting. This message is queued up until it is read (by repeatedly selecting
( MSSG J ), amplitude sweep is turned off, or the start amplitude is set again .
AB.OFF ... 30DB MAX S1" AN . C33
2033
Stop amplitude setting was turned off because the new start amplitude setting was set more than 30 dB
away from the stop amplitude setting. This message is queued up until it is read (by repeatedly selecting
( MSSG I ), amplitude sweep is turned off, or the stop amplitude is set again.

Changing between EMF and non -EMF amplitude modes could cause the increment and/or amplitude
settings to be reset to allowable values.
