Keysight EDUX1052A - To Verify Bandwidth (-3 Db)

24 Keysight InfiniiVision 1200 X-Series and EDUX1052A/G Oscilloscopes Service Guide
2 Testing Performance
To verify bandwidth (-3 dB)
This test checks the bandwidth (-3 dB) of the oscilloscope. In this test you will use
a signal generator and a power meter.
Table 6 Bandwidth (-3 dB) Test Limits
Models Test Limits
200 MHz Models All channels (-3 dB), dc to 200 MHz
100 MHz Models All channels (-3 dB), dc to 100 MHz
70 MHz Models All channels (-3 dB), dc to 70 MHz
50 MHz Models All channels (-3 dB), dc to 50 MHz
