Description and Model Differences

General Information - 2

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.
