Figure 2-4 U8903B Audio Analyzer Connections For Crosstalk Verification - Keysight U8903B Service Manual

Figure 2-4
2 Configure the U8903B generator output channels as follows:
– Connection type: Unbalanced
– Output impedance: 600 Ω
– Output grounding configuration: Floating ground
– Waveform: Sine
– Output state: OFF
3 Configure the U8903B analyzer input channels as follows:
– Connection type: Unbalanced
– Input bandwidth: 90 kHz
– Input coupling: DC
– Voltage detector type: RMS
– Trigger source: Immediate
– Multi-channel function: Crosstalk
– Sample size: 131072
4 The first test will measure the generator crosstalk from channel 1 to channel 2 in which
the Driving channel is channel 1 and the Measured channel is channel 2.
5 Set the U8903B analyzer Driving channel as the reference channel and the analyzer
input range of Vrms as given in the "Test record for crosstalk verification" on
page 102.
6 Set the U8903B analyzer Measured channel input impedance to 300 Ω and analyzer
input range to 0.32 Vrms.
7 On the U8903B generator, set the Driving channel output amplitude of Vrms as given in
the "Test record for crosstalk verification" on page
output amplitude to 0 Vrms.
8 Set the U8903B generator Driving and Measured channel frequency of f
the "Test record for crosstalk verification" on page 102.
