30 Agilent E1538A Enhanced Frequency/Totalize/PWM SCP
Rotational Pulse
Command Usage
Use SOURce:FUNCtion:RPULse (@<ref_channel>),(@<ch_list>) to
link channels in <ch_list> to the rotational pulse function. The channel in
<ref_channel> will be linked to the SENS:FUNC:RVEL function to provide
the rotational reference information to SOUR:FUNC:RPUL.
The commands:
SOURce:RPULse:POSition[:ANGLe] <degrees>,(@<ch_list>),
SOURce:RPULse:WIDTh[:ANGLe] <degrees>,(@<ch_list>), and
SOURce:RPULse:WIDTh:TIME <seconds>,(@<ch_list>) fix the
channels’ rotational pulse position (SOUR:RPUL:POS:ANGL), or the
rotational pulse width (SOUR:RPUL:WIDT:ANGL and :TIME) before the
INITiate command. The remaining pulse property - the property NOT
specified in one of these commands - will be controlled within the algorithm.
• <ch_list> specifies the SOUR:FUNC:RPUL channel(s) that will be set
to the property specified by the command syntax.
• For pulse position, <degrees> can range from -33,554,430 to 33,554,430
degrees, with a resolution of 1 degree. The pulse is positioned at
<degrees> modulo 360.
For pulse width, <degrees> can range from 0 to 360 degrees, with a
resolution of 1 degree.
• <time> specifies pulse width in seconds, ranging from .00000787 (7.87
µS) to .015624 (15.624mS), with a resolution of 238.4nS
The command:
SOUR:RPULse:VARType ANGLe | TIME,(@<ch_list>) specifies the
type of value that will be controlled (varied) by the algorithm.
• ANGLe specifies that the algorithm will send values of angle (in
degrees) to the channel(s).
TIME specifies that the algorithm will send values of time (in seconds)
to the channel(s).
• <ch_list> specifies the SOUR:FUNC:RPUL channel(s) that will be
controlled (varied) by the algorithm.
