personnel. Disconnect the power cord before removing the instrument covers and replacing components. Under certain conditions, even with the power cable removed, dangerous voltages may exist. To avoid injuries, always disconnect power and discharge circuits before touching them. DO NOT SERVICE OR ADJUST ALONE Do not attempt any internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.
WARNING: To avoid electrical shock hazard, disconnect power cord before removing covers. Refer servicing to qualified personnel. CAUTION: Before connecting the line cord to the AC mains, check the rear panel AC line voltage indicator. Applying a line voltage other than the indicated voltage can destroy the AC line fuses. For continued fire protection, replace fuses only with those of the specified voltage and current ratings.

2 Installation 2.1 Introduction This section contains installation information, power requirements, initial inspection and signal connections for the 4007B and 4013B signal generators. 2.2 Package Contents Please inspect the instrument mechanically and electrically upon receiving it. Unpack all items from the shipping carton, and check for any obvious signs of physical damage that may have occurred during transportation. Report any damage to the shipping agent immediately.
2.4 Instrument Mounting The 4007B and 4013B Function Generators are intended for bench use. The instrument includes a front feet tilt mechanism for optimum panel viewing angle. The instrument does not require special cooling when operated within conventional temperature limits. It may be installed in a closed rack or test station if proper air flow can assure removing about 15 W of power dissipation. 2.
1. Locate the fuse box next to the AC input connector in the rear panel. 2. With a small flat blade screwdriver, insert into the fuse box slit to pull and slide out the fuse box as indicated below. 3. Check and replace fuse if necessary. Fuse box Fuse box slit Check/Remove Fuse 2.7 Grounding Requirements For the safety of operating personnel, the instrument must be grounded.
UNIT AND THE FACILITY POWER FOR A CONTINUOUS EARTH GROUND PATH. THE POWER CABLE MUST MEET IEC SAFETY STANDARDS. 2.8 Signal Connections Use RG58U 50Ω or equivalent coaxial cables for all input and output signals to and from the instrument.
3 Operating Instructions 3.1 General Description This section describes the displays, controls and connectors of the function generator. All controls for the instrument local operation are located on the front panel.
4 Waveform Buttons 5 Rotary Knob 6 Cursor Keys 7 Output ON/OFF 8 SWEEP Button 9 UTIL Button 10 Units Keys 11 Numeric Keypad Select Sine, Ramp/Triangle, Square waveform shape Enable/Disable Output Selects Sweep function menu Utility menu 3.2 Display Window The function generator has a graphic LCD display that can display up to 124 x 32 dots. When you power-on the unit sine waveform is selected and current settings appear in the display.
1. Press the key that leads to the item to change. 2. Move cursor using cursor keys to the appropriate position in the numeric field (if applicable). 3. Use the rotary input or the numerical keyboard to change the value of the displayed item. Changes take effect immediately. 3.4 Connectors The function generator has two BNC connectors on the front panel where you can connect coaxial cables. These coaxial cables serve as carrier lines for output signals delivered from the function generator.
especially with sine and triangle waveforms. To ensure waveform integrity, follow these precautions: 1. Use good quality 50 Ω coaxial cable and connectors. 2. Make all connections tight and as short as possible. 3. Use good quality attenuators if it is necessary to reduce waveform amplitudes applied to sensitive circuits. 4. Use termination or impedance-matching devices to avoid reflections. 5. Ensure that attenuators and terminations have adequate power handling capabilities.
3.6.1 WAVEFORM Keys The keys select the waveform output and displays the waveform parameter menu (frequency, amplitude and offset). Sine Menu F1: FREQ – (Frequency) Selects and displays the frequency. Change the frequency setting using the cursor keys, rotary knob or numerical keys. F2: AMPL – (Amplitude) Selects and displays the Amplitude. Change the amplitude setting using the cursor keys, rotary knob or numerical keys. F3:OFST – (Offset) Selects and displays the Offset parameter.
The offset voltage has three ranges as follows: Output Voltage Range 1.01 volt to 10.00 volts 0.101 volt to 1 volt Constraints of Amplitude + Offset (Vp-p)/2 + |offset| <= 5 volts (Vp-p)/2 + |offset| <= 0.5 volts (Vp-p)/2 + |offset| <= 0.05 volts 0.010 volt to 0.100 volt F4:SYM – (Symmetry) When the Square waveform is selected, the SYMMETRY (Duty cycle) parameter is available. Change the duty cycle (square) by using the cursor keys, rotary dial or numerical keys.
3.6.2 UTILITY Key Utility Menu F1: RECALL – Recalls a previously stored front-panel setup from the selected buffer. Change the buffer number by using the rotary input knob. Valid storage buffer numbers are from 1 to 9. Buffer 0 is the factory default setup. F2:STORE – Stores the current front-panel setup to the specified storage buffer. Change the buffer number by using the data keys or the rotary input knob. Valid storage buffer numbers range from 1 to 9.
To select the sweep mode, press SWEEP, then press the function key that corresponds to the desired Sweep menu option, as shown: Sweep Menu F1: ON/OFF – Enables/disables the sweep function. Select between Sweep ON or OFF. F2: LIN – Selects the Linear sweep shape. F3: LOG – Selects the Logarithmic sweep shape. F4: SET – Defines the Sweep Start and Stop frequencies. Set Sweep Menu 3.7 ON Key Use this key to control the main output signal. When the output is active, the key will lit.
3.8 Cursor Keys Use these keys to move the cursor (when visible) either left or right. They are used in conjunction with the rotary input knob to set the step size of the rotary input knob. 3.9 Rotary Input Knob Use this knob to increase and decrease numeric values. The cursor indicates the low-order position of the displayed value which changes when you rotate the knob (for straight numeric entries only). For other types of data, the whole value changes when you rotate the knob. 3.
3.11 Memory The waveform generator uses non-volatile flash memory for storing the front panel settings. Up to 9 front panel settings can be stored (not including default settings). 3.12 Displaying Errors The waveform generator displays error messages when front-panel settings are either invalid or may produce unexpected results.
3.13 Quick Start This section explains how to generate various waveforms and modify the output waveform. * Generating a waveform output * Modifying waveform output * Storing and recalling a waveform generator setup 3.13.1 Selecting a Standard Waveform You can select several standard waveforms as: sine, triangle, square. Creating a standard waveform requires selecting the waveform type, parameters and their settings that define the waveform.
To set voltage offset: 1. Select a waveform to display its menu. 2. Press F3 :OFST to display the offset setting. 3. Use the rotary input knob or the numerical keys to set the voltage offset. To turn the voltage offset OFF, repeat the steps above, but set the offset voltage level to 0. 3.13.4 Storing and Recalling a Waveform Generator Setup You can store up to 9 front-panel setups inside the internal non-volatile flash memory.
Recalling Setups To recall stored front-panel setup: 1. Press UTILITY to display the menu. 2. Press F1:RECALL to select the Recall mode. 3. Use the rotary input knob to select a buffer number. Valid buffers numbers range from 0 to 9. Buffer 0 is a read-only buffer that contains the default power-on setup.
