c. The type BNC 50-ohm termination adapter supplied has a VSWR of less than
1.2:1 up to 600MHz. The adapter has a 5 watt max. power rating.
d. The high impedance probe tip supplied allows for direct high impedance
measurements up to 250MHz. However, a short wire should be substituted for the
ground lead when using above 100MHz to minimize the effects of ground lead in-
duction.
e. T h e main controls required to operate the voltmeter are on the front panel.
Several minor controls are on the rear panel.
