User Manual 3155Programming Reference 4-45OUTPut Subsys-temThis subsystem controls the characteristics of the output. It controlsfilter type and filter cutoff frequency. It is also used to control the syncoutput, source and position. Optional nodes were omitted from thesecommands. Factory defaults after *RST are shown in bold typeface.Parameter low and high limits are given where applicable.Keyword Parameter Form Default,Low Limit,HighLimit:OUTPut (?) {OFF|ON|0|1} OFF:FILTer (?) {NONE|25M|50M|ALL} NONE:SYNC (?) {OFF|ON|0|1} OFF:SOURce (?) {BIT|LCOMplete} BIT:POSition (?) 0,0,n:WIDTh (?) 4,4,100000:TTLTrig {1|2|3|4|5|6|7}[:STATe] (?) {OFF|ON|0|1} OFFOUTPut{OFF|ON|0|1}PurposeThis command turns the 3155 output on and off.• ON or 1 sets the output on• OFF or 0 sets the output offParameter typeDiscreteOUTPut?Response and defaultThe 3155 returns 1 if the output is on, or 0 if the output is off. Default value is 0.OUTPut:FILTer{NONE|25M|50M|ALL}PurposeThis command selects which filter is connected to the 3155 output. Observe the following restrictions whenyou try to use this command:1) Filter selection is not available when the instrument is set to output the standard sine waveform. In fact,the default waveform shape is sine. Therefore, filter selection is available for use only after you select adifferent waveform, or change the output mode to use.2) Filters are placed before the output amplifier. Therefore, do not expect the filters to remove in-band am-plifier harmonics and spurious.• NONE disconnects all filters from the output path• 25M connects the 25 MHz low pass elliptic filter• 50M connects the 50 MHz low pass elliptic filter• ALL connects both the 25 MHz and the 50 MHz filters in series
