Menu Description
Driven Ch Press the Driven Ch softkey to select the driven channel number from the generator.
Press the Freq Lock softkey to select the searching method for the fundamental frequency.
– Auto
Selecting Auto will allow the U8903B to search for the fundamental frequency automatically.
– Gen Lock
Freq Lock
Selecting Gen Lock will allow the U8903B to use the driven channel frequency value. You can select the generator
channel by setting the Driven Ch. This Gen Lock method is only useful if you use the internal audio generator.
– Custom
If you have a known input signal, you can define the fundamental frequency value by setting the searching method to
Custom and setting the frequency value in Fund Freq.
Press the Fund Freq softkey to set the fundamental frequency value. This setting is only available when Freq Lock is set to
Fund Freq
Custom.
Press the Sample Size softkey to select the number of samples to be acquired for the measurement.

Press the Input Range softkey to configure the input range settings.
– Auto Range
Enable or disable the auto input range.
If auto range is enabled, each analog channel input range is determined automatically, based on the level of the input
signal. If the input signal level changes beyond the ranging threshold, auto range will cause the input ranging circuits to
move up or down for a proper ranging.
If auto range is disabled, you can set a fixed input voltage range for each analog input channel.
Input Range
– Track 1st Ch
If Track 1st Ch is enabled, all the other channels will be set to follow the channel 1 range setting. Any changes made to
channel 1 range setting will be reproduced in the other channels. Disable the Track 1st Ch to set the individual
channels.
– Voltage Range
Set the input voltage range.
