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 SWEEP-
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.
- (LED s)
Indication of selected function.
- (pushbutton)
Mode selection: Triangle, Sine, Square, Pul-
se 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%.

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
terminated into 50Ω. The offset voltage is
available to all functions except for pulse and
activated by
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 fixed
pulse width amounts to 50%.
50Ω OUTPUT (BNC connector)
Short-circuit proof signal output of the
generator. The output impedance is 50Ω and
the max. output amplitude is 20 V
10 V respectively when terminated into 50Ω.
pp
–20dB, –20bB (pushbutton)
Two fixed 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.
