To store the instrument state

To store the instrument state

You can store up to three different instrument states in non-volatile memory. This enables you to recall the entire instrument configuration

with just a few key presses from the front panel. The following steps show 2 you how to store and recall a state.

1Set up the function generator to the desired configuration.

The state storage feature “remembers” the function, frequency, amplitude, dc offset, duty cycle, as well as any modulation parameters.

2Turn on the state storage mode.

Three memory locations (numbered 1, 2, and 3) are available to store instrument configurations. The instrument configuration is stored in non-volatilememory and is remembered when power has been off.

STORE 1

This message appears on the display for approximately 10 seconds. Repeat this step as needed.

3Store the instrument state in memory location “2”. 1 Use the up and down arrow keys to select the memory location.

STORE 2

To cancel the store operation, press Shift Store again or let the display time-out after 10 seconds.

4Save the instrument state.

The instrument state is now stored. To recall the stored state, turn to the next page.

1You can also use the knob or “enter number” mode to enter a memory location.
