Description
The HP 66311A Mobile Communications DC Source provides a stable, programmable dc source for
testing digital wireless communications products. It integrates a highly accurate voltage and current
meter with the capability to measure currents in the microampere range. The HP 66311A also has the
ability to measure and characterize output voltage and current waveforms.
The HP 66311A can source and measure currents up to 5 amperes for up to 7 milliseconds. Note that the
average current cannot exceed 3.0712 amps. If the unit attempts to draw current for longer than seven
milliseconds, the current limit amplifier will limit the current to 3.0712 amps.
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).

Front Panel Controls
The front panel has both rotary (RPG) 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 HP-IB
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.
