The AM 503B and AM 5030 current probe amplifiers let you use one probe to
simultaneously measure AC and DC current. The Amplifier converts the sensed
current into a proportional voltage signal that you can measure directly with an
oscilloscope.
The AM 503B and AM 5030 provide better linearity than other current
measurement systems because of a current feedback process used with the probe.
DC measurement capability and high bandwidth allow the Amplifier to
accurately represent square waves and fast-rise signals.
The AM 503B and AM 5030 provide these features:
Simultaneous DC and AC current measurements.
High sensitivity.
One-button autobalancing and probe degaussing.
No adjustments needed to match a current probe to an individual amplifier
(except for the A6303 current probe).
Probe trim adjust allows fine tuning of gain for increased accuracy.
The AM 5030 provides an additional feature:
Programmable control from a GPIB controlle
The AM 503B and AM 5030 systems may be used with the following Tektronix
probes:
A6312 (20 amps)
A6302 and A6302XL (20 amps)
A6303 and A6303XL (100 amps)
A6304XL (500 amps)
You can also use the CT-4 High-Current Transformer with the A6312, A6302,
and A6302XL current probes to extend their AC current measurement range to
20,000 peak amps
