The On/Off key illuminates. If a load is connected to the output, the front panel display will indicate that it is drawing current.
Page 97 3 User Information Impedance with Output Off The AC6900 Series instruments do not disconnect output from the internal circuits mechanically using switches and relays. Instead, when the output is turned off, the instruments electrically increase output impedance to limit the output without chattering. The approximate resistance in the high-impedance condition is shown below, so if the load is a battery or a similar device, a slight current may flow into the instrument and the load may be discharged.
Page 98 3 User Information Output ON & OFF Phase Without enabling phase control, the output turn-on will occur at random points in the output waveform. You can control both output-on and output-off phases by specifying a turn-on and turn-off phase in degrees, The default setting is zero degrees. You can specify values from 0 to 360 degrees. To enable the phase controls, toggle the On Phase and Off Phase softkeys to ON.

Page 110 3 User Information Programming Output Sequences A sequence is a series of settings—values such as the output voltage, frequency, and time—that are created and saved in advance, and are then recalled and run at a later time. Sequences are groups of executable units called steps. When a sequence is executed (run), its steps are executed in order, starting with the specified starting step.
Page 111 3 User Information Stat Out Turns the status signal output either on (checked) or off (unchecked). When the status signal output is turned on, the signal is output only while the step’s waveform is being output. Trig In Turns the trigger in signal either on (checked) or off (unchecked). When the trigger input is turned on, the sequence is paused after the previous step is finished, and the product enters a trigger input wait state.

Introduction This manual describes instrument programming using Standard Commands for Programmable Instruments (SCPI) over LAN, USB, and GPIB (optional).
Page 149 4 SCPI Programming Keywords Keywords, also referred to as headers, are instructions recognized by the instrument. Common commands are also keywords. OUTPut is a root keyword, STATe, COUPling, and PROTection are second-level keywords, and CLEar are third-level keywords. Colons ( : ) separate the keyword levels. The command syntax shows most commands (and some parameters) as a mixture of upper- and lower-case letters.
Page 150 4 SCPI Programming is the same as sending the following commands: FREQuency 100,90,110 FREQuency:MODE FIXed You can also combine commands of different subsystems within a message string. In this case, you must use a colon to return the command parser to the root level in order to access another subsystem. For example, you could specify the frequency and turn on the output as follows: FREQuency 100,90,110;:OUTPut ON The colon after the semicolon returns the command parser to the root.
Page 151 4 SCPI Programming Note that special values for numeric parameters such as MINimum and MAXimum are also accepted. Instead of selecting a specific value for the voltage parameter, you can substitute MIN to set the voltage to its minimum allowable value, or MAX to set it to its maximum allowable value. You can also optionally include the following engineering unit suffixes with numeric parameters: Parameter Default Unit...

Page 261 4 SCPI Programming Trigger System Overview The AC6900 Series has four different trigger subsystems. TRANsient - this subsystem is used to change the voltage and frequency settings. ACQuire - this subsystem is used to measure voltage, current, and power. SIMulation - this subsystem executes power line abnormality simulations. PROGram - this subsystem executes sequences.
Page 262 4 SCPI Programming Transient Trigger Example You can use the TRIGger:TRANsient subsystem to synchronize the changes in the output with triggers. This is useful when you want to synchronize the changes in the output to the operation of external devices, such as DC power supplies and electronic loads. The programmable parameters of the TRANsient group are AC voltage, DC voltage, and frequency.
Page 263 4 SCPI Programming If you repeatedly change the output, a trigger error (-210) may occur. By using the *OPC command, you can prevent this error.-> “Waiting for Operation Complete” TRIGger:TRANsient;*OPC Applies a trigger and waits until the output change is complete The INITiate:TRANsient command pulls the trigger subsystem out of the IDLE state and starts (or initiates) the trigger function.
Page 264 4 SCPI Programming INITiate:ACQuire;*OPC Initiates the acquire function and waits for completion. The INITiate:ACQuire command pulls the trigger subsystem out of the IDLE state and starts (or initiates) the trigger function. When set to BUS, the trigger subsystem enters the WTG (Waiting For Trigger) state.
Page 265 4 SCPI Programming When the trigger acquire source is set to IMMediate instead of BUS, the simulation starts immediately after INITiate:SIMulation. When the simulation finishes, the TRIGger subsystem enters the IDLE state again. If the ABORt command or an equivalent command is received when a simulation is being executed, the simulation is canceled, and the TRIGger subsystem returns to the IDLE state.

The status diagrams provide an graphical view of how the status registers and groups are interconnected.
Page 267 4 SCPI Programming Operation Status Group These registers record signals that occur during normal operation. The group consists of a Condition, PTR/NTR, Event, and Enable register. The outputs of the Operation Status register group are logically OR-ed into the OPERation summary bit (7) of the Status Byte register. See Status Registers for a description of each register.

Page 269 4 SCPI Programming Status Byte Register This register summarizes the information from all other status groups and stores STB and RQS messages as defined by the IEEE 488 standard. The *STB? query reads the status byte register and transmits the contents of the status byte register and the master status summary (MSS) message. The *STB? query does not change the status byte, MSS, or RQS.

Page 280 4 SCPI Programming Measurement Details This section summarizes the mathematical processing used to extract desired measurement values from arrays of digitized voltage and current data. I Required mathematical processing is similar for voltage and current. All raw measurements, i.e. individual A/D conversions and associated array elements, are understood to be DC coupled. Additional measurement considerations must include the effects of windowing (normally used to ensure stable readings), and any adjustments that must be made to correct for window gain (always less than unity when compared to a rectangular window).

Page 282 4 SCPI Programming Error and Limit Checking Basic Principles Range Error Checking Soft Limits Checking Settings Error Checking Output Coupling Error Checking Coupled Parameter Error Checking Basic Principles The AC6900 Series instruments include error checking measurements and soft limits that prevent unintended operations from being carried.
Page 283 4 SCPI Programming 2. In addition to the immediate DC and AC voltage, in Step mode the triggered voltage setting (VOLT:OFFS:TRIG or VOLT:TRIG, depending on the output coupling) is also checked to ensure that an accepted trigger does not cause an invalid state. 3.
Page 284 4 SCPI Programming Coupled Parameter Error Checking Inactive parameters generally are not checked for being within range or compliant with soft limits even if soft limits are active for the parameter type. This minimizes nuisance error messages when setting values for inactive parameters. Instead, checks are performed when the parameter is made active. However, parameter entries are always checked for being within the MIN and MAX values even if the parameter is inactive.
