NBS Type II Power Measurement System.
power output capability to drive a Positive, Intransic, Negative (PIN) diode
modulator, the other with a 300 mA maximum to drive a ferrite modulator.
d. Finally, the reference generator can be used as a 0-10 volt DC source.
Output impedance is less than 20 milliohms; available output current depends
upon the voltage setting. This output is short circuit proof, as are all other
outputs available at the front panel or either the bridge or the reference
