6.10.2 Restrictions in MG3633A command interchange mode
This paragraph describes the restrictions in MG3633A command interchange mode.
(1) Common items
• Exponent representation of numeric data is unavailable.
• The semicolon (;) is the only valid separator when multiple commands are sent on one line. Do not use the
comma (,).
• No header is added to talker data for a query command. Only numeric data is output.
(2) Frequency
• Frequency up and down (TFR and EFR) using the rotary knob are enabled by substituting the step key func-
tion. Using the step key and rotary knob to increase or decrease the frequency may not perform correctly
unless a frequency step value (FIS<Numeric><Freq term>) or frequency resolution (R0 to R9) is set.
• Resetting the frequency (ZFR) cannot be interchanged because the MG3641A/MG3642A does not have an
equivalent function.
• The frequency offset display function can be interchanged only with the multistatement description
(FOS<Numeric><Freq term>;SP12) of the offset frequency setting command (FOS<Numeric><Freq term>)
and offset display mode ON command (SP12) separated by a semicolon (;).
(3) Output level
• Output level up and down (TOL and EOL) using the rotary knob are enabled by substituting the step key func-
tion. Using the step key and rotary knob to increase or decrease the level may not perform correctly unless the
level step value (OIS<Numeric><Ampl term>) or level resolution digits (L0 to L2) are set.
• The level resetting function (ZOL) cannot be interchanged because the MG3641A/MG3642A does not have
an equivalent function.
• The level offset display function can be interchanged only with the multistatement description
(OOS<Numeric><Ampl term.;SP08) of the offset level setting command (OOS<Numeric><Ampl term>) and
offset display mode ON command (SP08) separated by a semicolon (;).
• If the output level setting (OL<Numeric><Ampl term>) or level step up or down (UOL, DOL) command is
executed in level continuous mode, the continuous mode is canceled.
• The command relating to the output level limiter (OLM<Numeric><Ampl term>, SP05, SP06) cannot be
interchanged because the MG3641A/3642A does not have an equivalent function.
