Keysight U8903B - Table 4-8 Channel 1 Vertical Scale Settings

Performance Verification for Digital Generator and Digital Analyzer 4
Keysight U8903B Service Guide 77
– SINE waveform amplitude: 1 FFS
– Digital output state: ON
4 Set the digital output sampling rate to F
SR
as given in “Test record for unbalanced
output level accuracy verification” on page 152.
5 Set the digital output level to V
DUT
as given in “Test record for unbalanced output
level accuracy verification” on page 152.
6 Configure the DSO8064A oscilloscope as follows:
– Timebase scale: 1 / (Sampling rate × 32 × 2)
– Channel 1 vertical scale: Refer to Table 4-8
7 Set the DSO8064A oscilloscope to measure the amplitude of Channel 1 and record the
measurement as V
measure
.
8 Compute the level accuracy using the following equation:
Level Accuracy (dB) = 20
× Log (V
measure
/ V
DUT
)
9 Repeat step 5 to step 8 for the rest of the V
DUT
as given in “Test record for unbalanced
output level accuracy verification” on page 152 to complete the verification of the
different voltages.
10 Repeat step 4 to step 9 for the rest of the F
SR
as given in “Test record for unbalanced
output level accuracy verification” on page 152 to complete the verification of the
different sampling rates.
