Information
model
305 Phasemeter (figure 1-1) represents a totally
new concept in the measurement of phase angle. A precision
phase angle measurement is obtained simply by connecting the
signals and reading the display. No adjustments are required
during normal use. model
305 senses the signal frequency and
adjusts its output time constant for maximum speed
commensurate with low ripple. It remains operational in the
presence of up to 10% high frequency noise. Model 305
sensitivity to waveform distortion is reduced over that of
other phasemeters which normally require filters to remove
distortion effects.
1-5. The use of the automatic dual mode switching allows for
continuous phase plotting between <-160° to > +340° with no
discontinuities. The front panel controls on model
305 main
frame are used only for self checking of the main frame and
calibration of remotely connected
Accessories such as a
recorder or printer.
1-6 . Standard
Plug-In units covering a frequency range
of 1 Hz to 11 MHz are available with model
305 Phasemeter.
Special
Plug-In units are available on request.
