                                    1-2. The Model 5200A is a guarded, precision AC Calibrator
designed for use in calibration laboratories and in
manufacturing environments. The Calibrator provides accurate
ac voltages from 100 μν to 120V rms, at currents up to 50
mA, and at frequenceis from 10 Hz to 1.2 MHz.
1-3. The amplitude of the output voltage is controlled by a
range selector switch and six decade switches. Any of seven
amplitude ranges (lmV, 10 mV, 100 mV, IV, 10V, 100V, and
1000V) may be selected. (The 1000V range is used only in
conjunction with a companion unit, the Model 5205A Precision
Power Amplifier). The decade switches can then be set for
any value from 10 to 120 percent of the selected range (each
range has a 20 percent overrange capability). Six-digit
resolution within the selected range provides steps as small
as 1 nV in the 1 mV range through 100 μν in the 100V range
(and 1 mV steps in the 1000V range). The amplitude can be
offset up to either ±0.3 percent or ±3 percent (selectable)
by means of a voltage error measurement feature. This
feature provides direct indications of percentage error
during calibration of voltmeters.
1-4. The frequency of the output voltage is similarly
controlled by a range selector switch and four decade
switches. Any of five frequency ranges (100 Hz, 1 kHz,
10 kHz, 100 kHz, and 1 MHz) may be selected. The decade
switches can then be set for any value from 10 to 120
percent of the selected range. Four-digit resolution within
the selected range provides steps as small as 0.01 Hz in the
100 Hz range through 100 Hz in the 1 MHz range. If desired,
the frequency can be phase-locked to an external reference
source connected by coaxial cable to a BNC connector on the
rear panel. The accuracy of the phase- lock feature is±l
degree (nominal).
1-5. The selected output of the 5200A is available at output
connectors located on both the front and the rear panels.
The front panel connectors are banana-type jacks and are
provided for high and low output lines, high and low sense
input lines, guard, and ground. The rear panel connectors
are a pair of pcb card-edge connectors accessed through
openings in the panel. One of the connectors provides
interconnection to the Model 5205A Precision Power Amplifier
(when used), and the other provides the selected calibrator
output (except ground) to any other external equipment
requiring it.
1-6. In addition to the regular calibrator outputs, a
quadrature output and a counter output are available at BNC
connectors on the rear panel. The quadrature output leads
the regular output in phase by 90 degrees. The amplitude of
the quadrature output is proportional to the setting of the
amplitude control decade switches. Regardless of the range
selected, the rms amplitude of this output will be anywhere
from IV, at minimum setting, to 12V, at maximum setting. At
full-range (100 percent) setting, the amplitude will be 10V
rms. The counter output is the same frequency as the other
outputs, but in pulse form. The pulses are fixed in
amplitude at +3V peak, and vary in width according to the
selected frequency range.
