GENERAL DESCRIPTION
The Model
5000 Phase Standard is a precision calibration
instrument which produces two digitally synthesized low
distortion sine waves over a frequency range of 1Hz to
100kHz and with Independently selectable amplitudes from
lOOmV to 100V. The phase angle between the two sinewaves is
selectable over a range extending between -999.999° and
999.999° with a resolution of im°. A fixed CFFSET, with the
same range as the PHASE is also selectable.
Function selection is made via front panel key switches and
is displayed on a vacuum fluorescent display having 32,
large (0.45")* bright dot matrix characters. The current
values of PHASE, FREQUENCY, REFERENCE AMPLITUDE and VARIABLE
AMPLITUDE are displayed at all times in the normal operation
mode. STANDBY and OPERATE modes, which allow the output
sinewaves to be reduced to zero and then restored to their
previous values, are also selectable via key switches.
A special key switch matrix simplifies data entry by
allowing the operator to increment any digit of the current
values of PHASE, FREQUENCY, REFERENCE AMPLITUDE or VARIABLE
AMPLITUDE with a single key stroke. A RESET key switch
allows the operator to quickly restore the initial settings
of the standard.
The Model
5000 has as a standard feature the IEEE-488
interface which is accessible from the rear panel. Any
function which can be entered manually can be programmed and
sent to the Phase Standard over the IEEE bus. A REMOTE lamp
on the front panel indicates when the standard is being
controlled by the IEEE bus. When this lamp is illuminated
data entry via the front panel is impossible; however, a
LOCAL key switch is provided which allows the operator to
regain local control.
The Phase Standard is designed to operate with line voltages
of 100V, 120V, 220V and 240V at frequencies of 50Hz or 60Hz,
A switch in the line cord receptacle on the the rear panel
permits the voltage selection. This receptacle also contains
a line filter which restricts the passage of high frequency
signals both from the Standard to the line and from the line
to the Standard.
The Phase Standard is contained in a 19" wide, 7” high and
17" deep (including rack handles) and may be used on the
bench or mounted in a standard relay rack.
