5 - Basic Set-up Examples
Requirement
Changing the Range
Press the soft-key labelled Range
•
Press the soft-key labelled Range again to change the range from Auto to Hold.
•
Auto mode auto-ranges in 6dB attenuator steps (i.e. 'range' maximums of 10Vpp, 5Vpp, 2.5Vpp,
etc., into 50Ω), with the amplitude range limited to 6dB to maintain waveform quality.
Selecting Hold mode disables auto-ranging; the attenuator setting is fixed and the amplitude
range is no longer limited.
With range set to Auto the amplitude and attenuators will switch automatically and optimal
performance will be realised. With range set to Hold a fixed attenuator setting is used for all
amplitude settings.
