4080 series Function & Arbitrary/Function Generators –Instruction Manual

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
