Function Changes and Parameter Defaults
The values set as parameters are not retained on change of
When the 9100 is transferred from, say, ELF
and must be re-programmed on re-entry if different values are required.
<CPD>
The 'character program data' determines the waveshape of the output signal. It can be chosen from eight alternatives:
Determines that subsequent selection of VOLT or CURR will choose DC hardware for the output voltage or current.
DC
Voltage or Current levels will be set subsequently using the VOLT <DNPD> or CURR <DNPD> commands.
SINusoid Subsequent selection of VOLT or CURR will choose AC hardware for the output voltage or current. Voltage or
Current RMS values will be set using the VOLT <DNPD> or CURR <DNPD> commands. Frequency values will
be set using the FREQ <DNPD> command.
Selects a pulsed voltage output, and determines that the mark/period ratio will be 0.5 for any related FREQ selection.
SQUare
High and low voltage levels will be set to default values of +5V and 0V unless otherwise set using the VOLT HIGH
and VOLT LOW commands.
Selects a pulsed voltage output and determines that the mark/period ratio will be set by selections of PULS PER,
PULSe
together with PULS WID or PULS DCYC. High and low voltage levels will be set to default values of +5V and
0V unless otherwise set using the VOLT HIGH and VOLT LOW commands.
IMPulse|TRIangle|TRAPezoid|SYMSquare
Subsequent selection of VOLT or CURR will choose AC hardware for the output voltage or current, with the
'Impulse, Triangular, Trapezoidal or Symmetrical Square' waveshape (refer to Volume 1, Section 4, paras 4.4.3.4 and
4.4.6.4). Voltage or Current RMS values will be set using the VOLT <DNPD> or CURR <DNPD> commands.
Frequency values will be set using the FREQ <DNPD> command.
Examples of using the FUNC element:
An example command message to select a Group 2 source of +10.5V from outside Group 2 would be:
Alternatively, to select a Group 3 sinusoidal current source of 200mA at 1kHz from outside Group 3:
To select (from outside Group 5) a pulsed signal of period 200 s and duty cycle 60%, switching between +3.5V and -1.5V:
FUNC PULS;:PULS:PER 2E-4;:PULS:DCYC 60;:VOLT:HIGH 3.5;:VOLT:LOW -1.5
Sources in the Same Group
When selecting a source from within the same group as the previous [SOURce] command, it is not necessary to prefix the FUNC
command.
Response to Query Version
The 9100 will return the appropriate <CPD> from the selection {DC|SIN|PULS|SQU|IMP|TRI|TRAP|SYMS} which
represents the present source 'shape'. If the 9100 is programmed in one of the impedance functions (Group 1 in the table), then it
will return NONE.
