Function Keys
These keys control the main function output. The [∧] up and [∨] down function keys
select between the main output functions. [FREQ], [AMPL] and [OFFST] select the
output frequency, amplitude and DC offset voltage. [ON/OFF] turns the output on and
off.
Output Selection Key
The [∨] key changes the output configuration from one of the three choices: unbalanced,
balanced and digital. Pressing the [∨] once moves one entry down the list; pressing the
[SHIFT](∧) moves one entry up the list.
Trigger Key
The [TRIGR] key begins singly triggered modified functions, like single sweeps or
bursts.
Modify Function Keys
These keys control the function output modification commands for sweeps, bursts or
bandwidth limited noise. The [∧] up arrow and [∨] down arrow keys select the
modification type. The [SWP/BURST] key turns the modification function on and off.
The other keys select different function modification parameters (start frequency, burst
depth).
Only modify functions that are allowable for the current function type (sine, square,
noise...) can be selected (i.e. sweep can be selected for sine or square, but not white
noise). Only modify parameters (START FREQ, STOP FREQ ...) that are valid for the
selected modify function can be changed. If a currently invalid modify parameter is
selected, the unit will beep and display “not APPL” (not applicable). If a function type
