Performance Tests 5-21
DS360 Ultra Low Distortion Function Generator
10. Output Impedance
These tests confirms the output source resistors of the DS360.
Setup
Connect the + BNC output of the DS360 to the DVM through the 50 Ω feed through terminator. Set the
DVM to AC volts, auto-ranging.
Procedure
1) Reset the DS360 (Turn power off, wait 2 seconds, turn power on w/ [CLR] pressed).
2) Measure the output voltage for Hi-Z output impedance and record the results on the test record.
3) Measure the output voltage for 600 Ω (unbalanced) output impedance.
a) Press
[SHIFT] [600]
[AMPL] [1] [V
RMS
]
b) Measure and record the output voltage on the test record.
4) Measure the output voltage for 50 Ω (unbalanced) output impedance.
a) Press the following keys
[SHIFT] [50]
[AMPL][1][Vrms]
b) Measure and record the output voltage on the test record.
4) Measure the output voltage for 600 Ω (balanced) output impedance.
a) Press the following keys
[∨] (output down) for balanced impedance.
[SHIFT][600]
[AMPL][1][Vrms]
b) Measure and record the output voltage on the test record.
5) Measure the output voltage for 150 Ω (balanced) out with a 50 Ω terminator.
a) Press the following keys
[SHIFT][150]
[AMPL][1][Vrms]
b) Measure and record the output voltage on the test record.
