Clobetasol propionate cream and ointment produced HPA axis suppression when used at doses as low as 2 g per day for 1 week in patients with eczema. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent corticosteroid.
BNC Connecotrs are usually applied to frequrencies below 3GHz and voltages below 500 Volts. BNC connectors exist in 50 and 75 ohm versions, matched for use with cables of the same characteristic impedance. The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in the mating ends.
oscilloscope has a sine wave with amplitude of 1 V, or a peak to peak voltage of 2 V. There are two ways to fix this: 1. With a BNC T connector, connect a 50 Î© terminal load to the input of the oscilloscope. 2. Set the oscilloscope to internal impedance of 50 Î©. On the oscilloscope, between the channel 1 and 2 terminals, and slightly above, press the MENU button. This menu button brings up the menu for channel settings. On the bottom of the right hand menu you will see the omega symbol (Î©). Pressing this button toggles the input impedance
