TI LTINORM Switch -
Provides vertical markers in the NORM (down) position. I n the T I L T (up) posi-
tion provides horizontal markers having a fixed amplitude of approximately 10%
of the horizontal display, when MARKER SlZE i s set t o minimum.
NOTE: Increasing the marker size will cause the horizontal marker t o t i l t toward
a vertical position. This feature is used to identify frequencies on Steep response
skirts.

This three position switch provides; large markers in its Lower position (12 V to
50mV peak-to-peak), small markers in its Center position (50mV t o 100uV volts
peak-to-peak) and rectified positive markers in its Up position. These rectified
markers are for use with X-Y recorders.
BNC connector provides a 16 volt peak-to-peak triangle wave, symmetrical about
ground, to drive the Horizontal (x) axis of the oscilloscope or other indicating
device. (An alternate connection is available at the Rear Panel).
BNC connector provides the combined markers and demodulated RF (when
DEMOD in is connected) for connection to the oscilloscope Vertical (y) axis
input.
BNC connector accepts the demodulated, swept, signal from the device under test
so RF markers may be added. (The combined signal is available at the SCOPE
VERT. OUTPUT connector).
Attenuator; Outer knob providescalibrated adjustment of the RF output in 10 dB
increments from 0 dBm t o -70 dBm; inner knob provides calibrated vernier ad-
justment of the RF output from +10 dBm to -10 dBm.
BNC connector provides a connection for RF output signal.
BNC connector accepts an externally generated continuous wave signal to produce
a frequency marker on the display.
Push button switch for A4 option (1 kHz square wave amplitude modulation).
BNC connector accepts an automatic leveling control signal from a remote moni-
tor when EXTIINT switch is in the EXT (up) position.
Closes the internal automatic leveling loop when in INT (down) position.
NOTE: When this switch is in the EXT position, and no external monitor is in
use, the RF output is unleveled and not controlled by the 2 0 d B vernier attenua-
tor.
Push button applies A.C. power to the power supply. The light indicates that the
instrument is operating.
