6.10.3 Restrictions in MG3631A/32A command interchange mode
This paragraph describes the restrictions in MG3631A/32A 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 (,).
(2) Frequency
• Frequency up and down (FU and FD) using the rotary knob are enabled by substituting the step key function.
Using the step key and rotary knob to increase or decrease the frequency may not perform correctly unless the
frequency step value (DF<Numeric><Freq term>) or frequency resolution digits (R1 to R7) are set.
(3) Output level
• Output level up and down (LU and LD) using the rotary knob are enabled by substituting the step key function.
Using the step key and rotary knob to increase and decrease the level may not perform correctly unless the step
value (DL<Numeric><Ampl term>) or level resolution digits (L2 to L4) are set.
• If output level setting (OL<Numeric><Amp term>) or stepping up or down (FU or FD) is executed in level
continuous mode, the continuous mode is canceled.
(4) AM modulation
• Only AM modulation settings using numeric data (AM<Numeric><AM term>) are valid. Stepping up or
down (MU or MD) cannot be used.
• Because the MG3641A/MG3642A has only one system of AM modulation, AM MIX SOURCE cannot be
used.
• The Ext1 connector of Mod Input is assigned as the external modulation input.
(5) FM modulation
• Only FM deviation settings using numeric data (FM<Numeric><Freq term> or FM<numeric><Freq term>)
are valid. Stepping up or down (MU or MD) cannot be used.
• The Ext1 connector of Mod Input is assigned as the external modulation input.
