General Information - 1 15 Remotely programming is accomplished from either the GPIB bus or from an RS-232 serial port. GPIB and RS-232 programming uses SCPI commands (Standard Commands for Programmable Instruments) that make the ac source programs compatible with those of other instruments. AC source status registers permit remote monitoring of a [...]

1 - General Information 16 Peak Current/Dynamic Power Capability The ac source can generate peak currents that exceed the rms current capability of the unit. This not only applies when operating in ac mode, but also when programming output pulses in dc mode. Although the unit will generate peak output currents up to 40A ( Agilent 6811B/6812B) or 80[...]

General Information - 1 17 ♦ as voltage increases, the I peak setting needs to be decreased. ♦ as frequency increases, the I peak setting can be increased. ♦ as load resistance decreases, the I peak setting needs to be decreased. Note that the purpose of programming the I peak current is to prevent the unit from activating its internal protec[...]

1 - General Information 18 RMS Current Limit Circuit The output rms current limit is adjustable to any value within the range of the unit. If the load attempts to draw more current than the programmed limit, the output voltage is reduced to keep the rms current within the limit. When the output voltage is reduced, the waveform shape is preserved. I[...]

General Information - 1 19 CAUTION: Programming the ac source output impedance into a load with a low impedance can cause output voltage instability, which may damage the ac source. Stability MUST be maintained when operating the ac source with programmable resistance or inductance. To check for stability, monitor the output voltage with an oscillo[...]

21 2 Installation Inspection Damage When you receive your ac source, inspect it for any obvious damage that may have occurred during shipment. If there is damage, notify the shipping carrier and the nearest Agilent Sales and Support Office immediately. The list of Agilent Sales and Support Offices is at the back of this guide. Warranty information [...]

Installation - 2 25 Wire Considerations NOTE: To minimize the possibility of instability on the output, keep load leads as short as possible bundle or twist the leads tightly together to minimize inductance Current Ratings Fire Hazard To satisfy safety requirements, load wires must be large enough not to overheat when carrying the maximum short-cir[...]

2 - Installation 26 ♦ Connect the phase 1 (1) sense terminals to the side of the load that connects to the corresponding output terminal. ♦ Connect the Neutral (COM) sense terminal connector to the neutral side of the load. ♦ Twist and shield all signal wires to and from the sense connectors. The sense leads are part of the ac source’s feed[...]

Installation - 2 27 Remote Sensing and OVP Considerations In remote sense applications, the voltage drop in the load leads subtracts from the available load voltage (see "Remote Sensing Capability" in appendix A). As the ac source increases its output to overcome this voltage drop, the sum of the programmed voltage and the load-lead drop [...]

2 - Installation 28 In example B, the FLT output of one unit is connected to the INH input of another unit. A fault condition in one of the units will disable all of them without intervention either by the controller or external circuitry. The controller can be made aware of the fault via a service request (SRQ) generated by the Questionable Status[...]

Installation - 2 29 RS-232 Interface The ac source provides an RS-232 programming interface, which is activated by commands located under the front panel Address key. When the RS-232 interface is selected, the GPIB interface is disabled. NOTE: Sending or receiving data over the RS-232 interface when not configured for REMOTE operation can cause unp[...]

2 - Installation 30 Hardware Handshake The RS-232 interface uses the DTR (data terminal ready) line as a holdoff signal to the bus controller. When DTR is true, the bus controller may send data to the ac source. When DTR goes false, the bus controller must stop sending data within 10 characters, and must not send any more data until DTR goes true a[...]
