Information
The
5790A AC Measurement Standard is a systems instrument
that measures ac voltage with the uncertainty of a thermal
transfer standard. You control the 5790A’s operation from
the front panel or remotely over the serial or IEEE-488
interface.
You can operate the
5790A in measurement mode or transfer
mode. In measurement mode, the
5790A operates as a digital
ac voltmeter with up to 8 digits of resolution. Measurement
mode uses an internal dc reference. In transfer mode, you
apply an external dc or ac reference source. The 5790A
automatically performs switching and calculations, and
displays the resulting ac-dc or ac-ac difference on the
vacuum fluorescent Control Display.
The
5790A covers a voltage range of 700 μν to 1000V (70 mV
minimum in transfer mode), and a frequency range of 10 Hz to
1 MHz. A wideband voltage option extends frequency range to
30 MHz. The
5790A is also compatible with
Fluke A40 current
shunts, which permit you to make ac-dc or ac-ac current
transfer measurements up to 20A. Refer to the Specifications
for details,
A variety of input connections allows you to use the one
that best suits your application. There are four sets of
input terminals on the 5790A, two 50Ω Type “N” connectors
and two sets of five-way binding posts. One 50Ω Type “N” and
one set of binding posts is dedicated to the ac measurement
and transfer modes. AC or DC voltages can be applied to
either input connection, allowing you to perform automated
ac-dc transfer measurements. The second Type “N” input
connection supports the optional wideband mode, and the
SHUNT binding posts are for
Fluke A40 Series current shunts.
Two patented internal standards contribute the most to the
5790A’s ability to measure rms ac voltage with such low
uncertainty. These two standards are a stable and precisely
variable dc source similar to the one in the
Fluke 5700A
Calibrator and a high- performance thermal rms sensor
similar to the one in the
Fluke 792A AC/DC Transfer Standard.
Reference amplifiers establish the accuracy and stability of
the internal dc source. A patented 26-bit digital-to-analog
converter (dac) provides the
5790A with the ability to
precisely vary its internal dc source. This is a pulse-width
modulated dac with linearity typically better than 0.2 ppm
of full scale.
On the ac side, the
Fluke rms sensor is similar in principle
to a thermal voltage converter (thermocouple), but has
faster settling time, low dc reversal error, higher
signal-to-noise ratio, and excellent frequency performance.
