Control elements of HM8030-6

DISPLAY (7 segment LED)
5-digit frequency meter. LED indicators for
mHz, Hz, kHz and s
SWEEP (push button) and Indication (LEDs)
Button activates internal sweep generator.
The LEDs indicate the function chosen with the
SWEEP-Button. Settings are changed with
or .
FREQUENCY (adjustment knob)
Continuous and linear frequency fine ad-
justment, with the setting range from 0.09
to 1.1 (approx 0.045 to 1.1 in 10 MHz-range)
overlapping the ranges selected with
FREQUENCY (2 pushbuttons)
Frequency range selection from 50 mHz to
10 MHz in 8 decade steps.
Indication of selected function.
Mode selection: Triangle, Sine, Square, Pulse
and Off.
TRIGGER OUTPUT (BNC connector)
This short-circuit-proof output supplies a
square signal in synchronism with the output
signal. It is TTL compatible and has a duty-
factor of approx. 50%.

FUNCTION

OFFSET (adjustment knob)
Adjustment of the positive or negative offset
voltage. This DC voltage can be super-imposed
on the output signal. The max. offset voltage
is ±5V (o.c.) or ±2.5V respectively when termi-
nated into 50Ω. The offset voltage is available
to all functions except for pulse and activated
by . In operation mode OFF (no function
activated) it can be used separatey. In pulse
mode the pulse width is set with this control
from 10% to 90%.
ON (pushbutton)
Activates the offset function except in pulse
mode. If the ON-button is pushed in pulse
mode, pulse width is set with the control
from 10% to 90%. In OFF-position the fi xed
pulse width amounts to 50%.
50Ω OUTPUT (BNC connector)
Short-circuit proof signal output of the gene-
rator. The output impedance is 50Ω and the
max. output amplitude is 20 V
respectively when terminated into 50Ω.
–20dB, –20bB (pushbutton)
Two fi xed attenuators, 20dB each. They can be
used separately. When both pushbuttons are
activated, a total attenuation of 40dB results.
Including the amplitude control
attenuation amounts to 60dB (factor 1000).
AMPLITUDE (adjustment knob)
Continuous adjustment of the output ampli-
tude from 0 to –20dB terminated into 50Ω.
