Getting Started Power Cord Options The standard TSG130A power cord is a 120 V, 15 Amp cord equipped with the standard North American three-prong power plug as shown in Table 1–16. The signal generator may be ordered with the other power-cord options shown in table 1–16.
This section describes the front panel controls, the rear panel connectors, and how to use them. For information on configuring the internal jumpers see TSG130A Jumper List, Table 7–2. For information on configuring the power supply for 110 VAC or 220 VAC operation, see Selecting the Power Supply Mains Voltage, page 7–1.
