Getting Started
Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.
2.1
Input Power Requirements
Input Power
The supply has a universal AC input that accepts line voltage and frequency input within:
100 – 240 V (+/- 10%), 50 – 60 Hz (+/- 5%)
100 – 127 V, 45 – 440 Hz
Before connecting to an AC outlet or external power source, be sure that the power switch is in
the OFF position and verify that the AC power cord, including the extension line, is compatible
with the rated voltage/current and that there is sufficient circuit capacity for the power supply.
Once verified, connect the cable firmly.
The included AC power cord is safety certified for this instrument operating in rated
range. To change a cable or add an extension cable, be sure that it can meet the
required power ratings for this instrument. Any misuse with wrong or unsafe cables
will void the warranty.
2.2
Output Connections
The waveform generator output circuits operate as a 50 Ω voltage source working into a 50 Ω
load. At higher frequencies, a non-terminated or improperly terminated output may cause
aberrations on the output waveform. In addition, loads with an impedance less than 50 Ω will
reduce the waveform amplitude, while loads with an impedance greater than 50 Ω will increase
waveform amplitude.
Excessive distortion or aberrations caused by improper termination are less noticeable at lower
frequencies, especially with sine and triangle waveforms. To ensure waveform integrity, follow
these precautions:
