4. OPERATING INSTRUCTIONS
4.1 Installation
This section contains installation information, power requirements and initial inspection and signal
connections for the 4080 series generators.
Mechanical Inspection
This instrument was carefully inspected before shipment. Upon receipt, inspect the instrument for
damage that might have occurred in transit. If any sign of damage is found, notify your B+K
Precision distributor.
Instrument Mounting
The 4080 Series is intended for bench use. The instrument includes a handle adjustable for
optimum panel viewing angle. The instrument does not require special cooling when operated
within conventional temperature limits.
Power Requirements
The 4080 Series can be operated from any source of 99V to 242V AC and frequency of 48Hz to
63Hz. The maximum power consumption is 35 VA. Replace fuses with the same type, according to
the rating indicated on the rear panel of the instrument.
The instrument power fuse is located in a fuse compartment below the AC input receptacle. To
access the fuse, first disconnect the power cord and then remove the fuse cartridge.
Power-on procedure
Turn on the instrument by pressing the power key on the front panel of the unit. The display should
be flashing “BK PRECISION” for 2 seconds followed by the model number. e.g. .“4084AWG” for 1
second. By default, the instrument will enter the standard waveform (“SW”) mode with the
frequency set to 10.00000000 kHz and the waveform annunciator displaying the “~ “ symbol. If
the Power ON configuration in the systems menu was modified, the parameters of the last operation
before power-down will be displayed.
4.2. Main operating modes
“SW” standard waveform mode
In this mode, the generator outputs any of the 27 build-in waveforms, including the 2 “main
waveforms” sine and square. This also includes the 8 user programmable arbitrary waveforms
(models 4084AWG and 4086AWG only). For most waveforms, you can set frequency, amplitude
and DC offset. In this mode, modulation and sweep is not active and all annunciators in status area 4
are turned off. When modulation or sweep is enabled, press【shift】 【SW】to return to this mode.
Modulation, Pulse and Sweep Mode
In this mode, the generator operates like a conventional function generator and the Arb annunciator
is turned off. The user can select one of the modulation modes AM, FM, FSK, PSK, Burst or sweep
mode. The 2 main waveforms sine and square can be used as carrier signal.
There is a close, reciprocal relationship between the modulation/sweep mode and the standard
