Description and Model Differences

The Agilent 66111A Fast Transient DC Source is a high performance dc power source that provides peak current sourcing and rapid, basic measurements in a compact, half-rack box. It is designed to simplify the testing of digital wireless communications products. Excellent voltage transient response characteristics prevent test interruptions due to triggering of low voltage phone shutdown. The 15 volt source and 5A peak current capability provides compatibility with a number of communications standards, including: GSM, CDMA, TDMA, PCS, DECT, TERA, PHS, NADC, PHS, and others. Figure 2-1 describes the output characteristic of the dc source.

The Agilent 66311B Mobile Communications DC Source is a high performance dc power source that provides all of the capabilities of the Agilent 66111A plus fast dynamic measurement and analysis of voltage and current waveforms. Dynamic measurement and analysis of current waveforms combined with precision current measurement let you characterize cellular phone current requirements under all operating conditions.

The Agilent 66309B Mobile Communications DC Source includes all of the capabilities of the Agilent 66311B with the addition of a second, electrically-isolated output. Figure 2-2 describes output characteristic of this second output, which is primarily used to provide voltage or current for a charger input on the device under test. The second output has all of the basic programmable features as the main output, with the exception of the waveform measurement capability, the open sense lead detect capability, overvoltage protection, and low current range.

The Agilent 66311D and 66309D Mobile Communications DC Sources also contain an auxiliary DVM, with input terminals located on the rear panel. This provides limited, low voltage dc and ac measurement capability, which can be used to monitor test point voltages on the unit under test as well as on the test fixture. The common mode voltage range is from −4.5 Vdc to +25 Vdc relative to the minus terminal of output 1. The DVM is programmable from the front panel of the instrument as well as remotely using SCPI programming commands.

Front Panel Controls

The front panel has both rotary and keypad controls for setting the output voltage and current. The panel display provides digital readouts of a number of output measurements. Annunciators display the operating status of the dc source. System keys let you perform system functions such as setting the GPIB address and recalling operating states. Front panel Function keys access the dc source function menus. Front panel Entry keys let you select and enter parameter values. Refer to chapter 5 for a complete description of the front panel controls.

Remote Programming

NOTE: When shipped, all dc sources are set to the SCPI programming language.

On Agilent 66111A and Agilent 66311B/D units you can change the programming language from SCPI to COMPatibility language. Press the front panel

to scroll to the LANG command, press

to select COMP, then press Enter. The

language setting is saved in non-volatile memory.

The dc source may be remotely programmed via the GPIB bus, and on Agilent 66111A and 66311B/D units, from an RS-232 serial port. GPIB programming is with SCPI commands (Standard Commands for Programmable Instruments), which make dc source programs compatible with those of other GPIB instruments. Dc source status registers allow remote monitoring of a wide variety of dc source operating conditions. A Compatibility language mode is also included on Agilent 66311A and 66311B/D units to make the dc source compatible with the Agilent 6632A, 6633A, and 6634A Series dc power supplies (refer to appendix E). Note that the compatibility features of this unit are limited to the features that were originally available on Agilent 6632A, 6633A, and 6634A units.

Output Current

Figure 2-1. Dc Source Output 1 Characteristic

The dc source is capable of providing a constant dc output of 15 volts with up to 3 amperes of current. It is capable of sourcing peak currents of up to 5 amperes -- provided the peak current pulse does not exceed 7 milliseconds, and the average current requirement does not exceed 3 amperes. If the unit attempts to draw current for longer than seven milliseconds, the current limit amplifier will limit the current to a maximum of 3.0712 amps. The peak current capability is illustrated by the dotted line in Figure 2-1.

NOTE: To source up to 5 amperes of current for up to 7 milliseconds, the current limit must

be programmed for greater than 3 amperes (up to a maximum of 3.0712 A).

The dc source can operate in either constant voltage (CV) or constant current (CC) over the rated output voltage and current. Although the dc source can operate in either mode, it is designed as a constant voltage source. This means that the unit turns on in constant voltage mode with the output voltage rising to its Vset value. There is no command for constant current operation. The only way to turn the unit on in constant current mode is by placing a short across the output and then enabling or turning the output on.

Note that the dc source cannot be programmed to operate in a specific mode. After inital turn-on, the operating mode of the unit will be determined by the voltage setting, current setting, and the load resistance. In figure 2-1, operating point 1 is defined by the load line traversing the positive operating quadrant in the constant voltage region. Operating point 2 is defined by the load line traversing the positive operating quadrant in the constant current region.

2 - General Informat ion

Figure 2-1 also shows a single range − two quadrant capability. This means that the dc source is capable of sourcing as well as sinking current over the output voltage range from zero volts to the rated voltage. This negative current sinking capability provides fast downprogramming of the output of the dc source. It can also be used to sink current from a battery charger, thus providing battery charger test capability. The negative current is not programmable, and varies linearly from approximately 1.2 amperes at the full rated voltage, to approximately 2.8 amperes at zero output voltage.

NOTE: If you attempt to operate the dc source beyond its output ratings, the output of the unit

may become unregulated. This is indicated by the UNR annunciator on the front panel. The output may also become unregulated if the ac line voltage drops below the minimum rating specified in Appendix A.

Output 2 Characteristic

As shown in the following figure, Agilent 66309B/D units have a second output rated at 12 V and 1.5A. The second output has all of the primary programmable features as the main output, with the exception of the waveform measurement capability, the open sense lead detect capability, overvoltage protection, and low current range.

Option 521 Description (Agilent 66309B/D only)

Option 521 consists of the following enhancements to the output capabilities of Agilent models 66309B/66309D:

♦ Solid-state relays to connect and disconnect the output of the dc source.

The relays are available on the output and sense terminals of outputs 1 and 2. When the solid state relays are open, the output impedance is effectively raised to about 500k ohms for output 1, and about 200k ohms for output 2. Note that the relays open only in response to an Output OFF command.

♦ The ability to either Hot switch or Dry switch the solid state relays.

With Hot switching, the relays control the on/off characteristics of the voltage at the output terminals. With Dry switching, the power mesh controls the on/off characteristics of the voltage at the output terminals. In general, Hot switching activates the relays when current is flowing through them. Dry switching activates the relays when no current is flowing through them. You can specify different relay options for the Output ON and Output OFF commands. The following table describes the actions that occur based on the relay mode selection in response to the ON or OFF commands.

The relay modes are stored in non-volatile memory. The last selected mode will be restored when the unit is turned on. When shipped from the factory, the relay mode for both output 1 and output 2 is set to Output ON Hot, Output OFF Hot (HH). The *RST command has no effect on the relay mode.

NOTES: Even with open sense lead detection enabled, the dc source does not check for open

sense leads when output 1 is enabled if the Output ON relay mode is set to Hot. On output 1 and output 2, with the Output OFF relay mode set to Hot, any external

output capacitors will not be downprogrammed or discharged. This is because the output relay opens prior to the downprogramming of the power mesh.

With either output 1 or output 2 disabled, the output voltage readback will not be correct. This is because the sense relay is open, effectively breaking the readback path. The voltage readback will be a small negative number.

Installation and Operation Checklist

Check the Output Compensation

 Check that the output compensation of the dc source is appropriate for your application. Refer to

“Output Compensation” in this chapter. High mode provides the best transient response and can be used with phones having input capacitances from 5 to 12000µF. Note that if the last two digits on the front panel display are fluctuating when the phone is in standby, you may want to set the output compensation to Low mode. Low mode is used when testing phones having input capacitances from 0 to 12000µF. Standard dc sources are factory-set to Low mode.

Check the Phone Connections

 If you ARE remote sensing, are the + and − sense leads connected ONLY at the test fixture and within 20 inches of the phone contacts? For best performance, the distance from sense lead termination

to the phone contacts should be as short as possible. Refer to “Lead Resistance” in this chapter. If your unit has a remote sense switch on the back, make sure it is set to the Remote position (out).

 If you are NOT remote sensing, are the sense jumpers installed in the output connector? Ensure that the output connector plug is installed in the unit with its supplied sense jumpers in place. Without sense jumpers, the unit goes into a protect state with the output disabled. If your unit has a remote sense switch on the back, you don't need sense jumpers. Make sure the switch is set to the Local position (in).

Check the Operating Settings and Conditions

 Are you able to communicate remotely with the dc source? If not, check that the address is set correctly. Refer to “GPIB Address” in the User’s Guide. If your unit has both SCPI and COMP language settings, check that the programming language is set correctly. Refer to “Language setting” in chapter 5.

 Is the Prot or Err annunciator on the front panel on? If yes, clear the fault condition before continuing. Refer to “Clearing Protection” in chapter 5.

 Is the Overvoltage circuit shutting the unit down? If yes, you can disable the overvoltage circuit. Refer to “Clearing Protection” in chapter 5.

 Are the front panel readings unstable? If yes, check that the front panel sampling rate is correct. Also check the setting of the output compensation. Refer to “Front Panel Measurements” in chapter 5 and “Output Compensation” in this chapter.

Additional Agilent 66311/66309 Operating Settings Checks

 Are you measuring dynamic output currents? If yes, check that the current detector is set to ACDC. Refer to “Front Panel Measurements” in chapter 5.

 Are you measuring output currents under 20 mA? If yes, check that the current range is set to LOW. Refer to “Front Panel Measurements” in chapter 5.
