mV illuminates in the display window, indicating the selected
units.
While the secondary parameter STEPTIME is selected,
sets the sweep mode to sweep amplitude or frequency.
CLEAR
Used before ENTER is pressed to cancel a numeric entry
and to reset the display.
After ENTER is pressed, clears a settings entry error and
resets the display to the last legai value.
can be used to blank the display or lift the pen, thus avoiding
plotting aberrations.
SYNC OUT
Provides a TTL signal at the frequency and phase of the
sine or square wave, iow frequency of the !M signals, the
envelope of the burst signal, or a squared version of the
external input signal.
EXT INPUT Triangle
Differential input which is connected to internal gain and
output attenuation circuits when the EXT function is
selected.

Also used after STORE or RECALL is pressed to cancel
the STORE or RECALL operation and reset the display.
ENTER
Enters a valid numeric entry into the current operating
setup. Pressing ENTER is not required when selecting a
source impedance, or when STOREing or RECALLing
settings.
@ INST ID
Causes the SG 5010 to display its GPiB address, and if
USER REQUEST and RQS commands are enabled, gener¬
ates a Service Request (SRQ) over the GPIB. This button is
also used with the RECALL button to change the GPIB ad¬
dress. Refer to Section 3, Programming.
(?) CONNECTORS
BURST GATE
Input connector for TTL trigger signal to initiate burst signal
generation (in BURST trigger mode), or to gate the output
signal (in BURST gated mode).
RAMP OUT
Provides a staircase ramp voltage that corresponds to
the sweep steps. Ramp begins at 0 V for the sweep start
and ends at 10 V for the sweep stop. The number of steps
between 0 and 10 V equals the selected number of sweep
steps.
PEN LIFT
Provides a TTL signal that goes low during frequency or
amplitude transitions in a sweep. When plotting frequency
response or distortion on an XY display or XY plotter, this
+ /- OUTPUT, COM
Banana jack connectors carrying the output signal. The
- and + OUTPUT connectors carry the output signal in
both balanced and unbalanced modes. The COM connector
provides access to the CT in the balanced mode and is tied
to the - OUTPUT connector in the unbalanced mode,

Chassis ground connector.
(?) Release Latch
Puli to remove plug-in.
OPERATORS FAMILIARIZATION
General Operating Information
With the SG 5010 properly installed in the power module,
allow twenty minutes warmup time for operation to specified
accuracy; 60 minutes after storage in or exposure to a high
humidity (condensing) environment.
Power-up Sequence
When powered up, the SG 5010 performs a diagnostic
self-test to check the functionality of the instrument ROM
and RAM, and some hardware circuits. It also illuminates all
front panel LED and indicators. If a self-test error is de¬
tected, a three digit error code appears in the readout win¬
dow, indicating an internal malfunction. Should this occur,
refer the condition to qualified service personnel. The
SG 5010 does not respond to front panel controls until the
error is cleared. Pressing the CLEAR button clears the error
code from the readout window and allows the instrument to
complete initialization, but does not dear the condition caus¬
ing the error code.
