DIAL LOCK - This button when pressed locks the
dial to prevent accidental data modification. It toggles
between lock and unlock while its associated LED turns
on and off to indicate its status.
3-3-4. Output Control Buttons
OUTPUT - The output button enables or disables
the signal at the main output connector. The light above
the OUTPUT connector is associated with this button.
FILTER - The FILTER button applies or removes
filters from the output signal. The light left to the FIL-
TER button is associated with this control.
3-3-5. Instrument Setups Buttons
STORE - The STORE button when pressed allows
storage of front panel setups. Using this function is
described later in this manual.
RECALL - The RECALL button when pressed initiates
recalling process of previously stored front panel
setups. Using this function is described later in this
manual.
3-4. Connectors
The connectors are used for connecting the Model 8024
to the unit under test.
1. SYNC OUT - The SYNC OUT connector outputs
fixed amplitude pulses. In most cases, the leading edge
of the SYNC output is synchronous with the leading
edge at the main output connector.
2. OUTPUT - The OUTPUT connector is used as
the main output for the function generator. Output is
driven from a 50Ω source. Special care should be taken
when these outputs are connected to the device under
test because these outputs are capable of delivering
amplitudes up to 20Vp-p.
3-5. Display and Indicators
1. DISPLAY - The function of the numeric display
is to indicate the value of the various parameters. The
8024 is using of a 2-line, 16-character LCD display.
The display is back-lit to enhance the LCD readout.
The display is also used to indicate other information
such as messages, errors, and more.
2. INDICATORS - 25 indicators are located on
the front panel. These indicators are used as pointers
to a selected menu, operating modes, etc.
3-6. Rear Panel Familiarization
There are a number of connectors and switches on the
rear panel. Their function is described in the following.
AC RECEPTACLE - Power is applied through the
power cord to the 3-terminal AC receptacle. Note that
the selected ac line voltage is marked on the line voltage
selector switch.
LINE SELECT SWITCH - The LINE SELECT
switch selects one of the primary voltages which are
marked on both sides of the switch.
LINE FUSE - The line fuse provides protection
for the AC power line input. For information on replacing
this fuse, refer to Section 5.
IEEE-488.2 CONNECTOR - This connector is
used for connecting the instrument to the IEEE-488.2
bus.
TRIG IN - The TRIG IN connector is used for
applying an external triggering source to the function
generator. This input accepts TTL signals only.
CLOCK IN - The CLOCK IN is used as an input
to receive a reference signal for synchronizing the
Model 8024 to other instruments.
3-7. Power-Up Procedure
The basic procedure of powering up the Model 8024
is described below.
1. Connect the female end of the power cord to
the AC mains receptacle on the rear panel. Connect
the other end of the power cord to a grounded AC
outlet.
WARNING
Operating Instructions
Be sure the power line voltage agrees
with the indicated value on the rear
panel of the instrument. Failure to
heed this warning may result in instrument
damage. The instrument is
equipped with a 3-wire power cord
designed to be used with grounded
outlets. When the proper connections
are made, the instrument chassis is
connected to the power line ground.
Failure to use a properly grounded
outlet may result in personal shock
hazard.
2. Turn on the mains power by pressing and releasing
the POWER switch on the front panel.
