1 POWER button : Push in the button, then the power will be supplied and the
display will light up. The power is off when push the button
again to the flat position.
2 UNIT keys : In ‘Normal’ mode, these keys are used to assign the unit and
to set the entered value. For example, you can use dBm,
Vrms, and Vpp to set the output amplitude. They can be used
to set frequency (MHz, kHz, Hz), OFFSET, PHASE, etc.
In STOR or RECL modes, they are used as ‘Enter’.
3 SHIFT key : Press this key to set the shift mode, and the SHIFT LED will
light up. For example, press [SHIFT] + [DEFAU] can recall the
default value of this instrument.
4 ENTRY keys : [ 0 ] ~ [ 9 ], [ . ], and [
± ] keys are used to input value. A unit
key should be pressed to set the entered value.
[ CLR ] key is used to delete the entered value entirely and
bring back the previous value.
[ STOR ] key stores the settings into memory.
[ RECL ] key recalls the system settings from memory.
5 SWEEP/
MODULATE keys : These keys control the functions of sweep and modulation.
[ ] and [ ] keys select the carrier waveform.
[AM], [FM], and [PM] keys set the mode of modulation.
[ LIN ] and [ LOG ] keys set the sweep method.
[ MOD ON/OFF ] initiates sweep or modulation function.
As to the functions of [STAR], [STOP], [SPAN], and [RATE]
keys, please refer to the instruction in Chapter 6.
6 MODIFY keys : These keys set the size and the increasing or decreasing
mode of steps.
7 FUNCTION keys : These keys controls the output functions.
[ ] and [ ] keys select the output signal from arbitrary wave
(ARB), sine wave, triangle wave, etc.
[ FREQ ] key sets the frequency of output.
[ AMPL ] key sets the amplitude of output.
[ OFFSET ] key sets the DC level of output.
[ PHASE ] key sets the phase in PSK modulation mode.
8 MAIN OUTPUT BNC : This is the BNC connector that outputs all main signals.
Output resistance is 50
Ω.
9 SYNC OUTPUT BNC : This is the synchronous output BNC connector that outputs a
TTL-level signal.
10 Interface LEDs : These LEDs indicate the current status when operating with
the GPIB interface bus.
11 Parameter display : This 11-digit display presents the parameter values and
information about the current status.
12 Unit/Function LEDs : These LEDs indicate the unit of the figures on display and the
functions that are currently being used.
