Specifications

Table 1-2 lists the performance specifications for the Agilent 662xA power supplies. Performance specifications describe the instrument’s warranted performance. The service manual, Option 9l0, contains procedures for verifying the performance specifications.

Table 1-3 lists the supplemental characteristics for the Agilent 662xA supplies. Supplemental characteristics are type-tested or typical values, which are based on a product sample and, while representative, are not guaranteed.

Qualifying Conditions

All performance specifications apply over the full operating temperature range of the power supply (0 to 55°C) unless otherwise specified. All regulation, accuracy, etc. specifications are plus or minus the values listed. All measurements are made at the rear terminals of the supply with a resistive load and local sensing unless otherwise specified. Voltage measurements are made from the + S to the - S terminals. Overvoltage measurements are made from the + V to the - V terminals. + Current refers to the output acting as a current source while - Current refers to the output acting as a current sink.

Definitions

Load effect: Maximum steady state change in the regulated output parameter due to a change in load resistance on the output in question.

Source effect: Maximum steady state change in the regulated output parameter due to a change in the source voltage within rated values. (Expressed as a percentage of setting plus a constant).

Cross regulation: Maximum steady state change in the regulated output parameter due to a change in load resistance on any other output(s).

Programming accuracy: (Calibration temp ± 5°C) Maximum difference between the programmed value and the actual output. (Expressed as a constant plus a percentage of the setting.)

Readback accuracy: (Calibration temp ± 5°C) Maximum error in reading back an output parameter. (Expressed as a constant plus a percentage of the reading).

Output response time: Beginning at the time the power supply has finished processing a VSET command (change output voltage), the maximum time for the output voltage to settle to within a settling band about the final value from any specified operating point. This value must be added to the command processing time to obtain total programming time (see Figure 1-3). Time constant is the maximum time required for the voltage to reach 63% of its final value.

Temperature coefficient: Maximum change in the regulated output parameter per °C change in ambient temperature after a 30 minute warmup. Expressed in parts-per-million plus a constant per °C (plus a constant for readback temperature coefficient).

Long Term Drift: Maximum change of regulated output voltage or current during an 8-hour period following a 30 minute warmup, with all influence and control quantities maintained constant. Expressed as a percentage of setting plus a constant.

Short Term Drift: Maximum change of regulated output voltage or current within 30 minutes after a line and/or load change. Expressed as a percentage of setting plus a constant.

Output Noise (PARD): PARD replaces the former term ripple and noise. PARD is the periodic and random deviation of dc output voltage or current from its average value, over a specified bandwidth and with all influence and control quantities maintained constant.
