Measurements Using the Auxiliary Control Fields:
•From Controls select Off to update the display after each sweep, or Pk
Hold to retain the highest input value for each point in succ essive sweeps.
•Input Atten sets the input attenuator to Automatic or Hold. If Hold is
selected, a specific level can als o b e selected.
•From Sensitivity select Normal for normal input sensitivity, or High for
increased input sensitivity (<1 µV) to locate low level signals. Sensitivity
also is used to set the vertical scale (dB/Div).
NOTE: Using High Sensitivity may cause erroneous amplitude or AM side-band
amplitude measurements.
•From Normalize
− select Save B to save the current trace (can only be perf o rm ed w he n
A Only is selected).
− select to display a continuously updated screen (normal operation).
− select to display the difference between the trace saved (using S ave
B) and the current tr ace.
Marker Indicators:
•Marker Freq MHz changes the units that the marker frequency is
displayed in.
•Marker Lvl dBm changes the units that the marker amplitude is
displayed in.
