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 4014B and 4040B 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 4014B and 4040B 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.
There is a 1A, 250V rated slow blow fuse at the AC input. Should the fuse ever get blown, follow the steps below to replace: 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.
WARNING TO AVOID PERSONAL INJURY DUE TO SHOCK, THE THIRD WIRE EARTH GROUND MUST BE CONTINUOUS TO THE POWER OUTLET.

Sync Out Connector Use this connector to output a positive TTL sync pulse generated at each waveform cycle. Modulation In Connector 5V p-p signal for 100% modulation, 10Kohms input impedance with DC - >20 KHz bandwidth. 3.5 Output Connections The waveform generator output circuits operate as a 50 Ω voltage source working into a 50 Ω load. At higher frequencies, non terminated or improperly terminated output causes aberrations on the output waveform.
If there is a DC voltage across the output load, use a coupling capacitor in series with the load. The time constant of the coupling capacitor and load must be long enough to maintain pulse flatness. Impedance Matching If the waveform generator is driving a high impedance, such as a 1 MΩ input impedance (paralleled by a stated capacitance) of an oscilloscope vertical input, connect the transmission line to a 50 Ω attenuator, a 50 Ω termination and to the oscilloscope input.

4.3 Message Exchange Protocol The device decodes messages using the Message Exchange Protocol similar to the one defined in IEEE 488.2. The following functions implemented in the MEP must be considered: 4.3.1 The Input Buffer The device has a 128-byte long cyclic input buffer. Decoding of remote messages is begun as soon as the input buffer is not empty, that is, as soon as the controller has sent at least one byte to the device.
4.3.3 Response Messages The device sends a Response Message in response to a valid query. All queries return a single Response Message Unit. 4.4 Instrument Identification The *IDN? common query is used to read the instrument's identification string. The string returned is as follows: BK, MODEL 4040B,0,V0.1 The “V0.1” reflects the firmware version number and will change accordingly. 4.5 Instrument Reset The *RST common command effects an instrument reset to the factory default power up state. 4.
or query. The Program Message is terminated by the Program Message Terminator. The Program Message Terminator consists of optional white space characters, followed by the Linefeed (LF) character (0x0A). The Program Message Unit can be divided into three sections as follows: a) Program Header The Program Header represents the operation to be performed, and consists of ASCII character mnemonics.
freq 1000 freq 1e3 b) Program Header Separator The Program Header Separator is used to separate the program header from the program data. It consists of one or more white space characters, denoted as . Typically, it is a space. c) Program Data The Program Data represent the values of the parameters being set, for example, the '1KHZ' in the above examples. Different forms of program data are accepted, depending on the command.
ON or OFF or numeric. A numeric value is rounded to an integer. A non-zero result is interpreted as 1 (ON), and a zero result as 0 (OFF). Queries return the values 0 or 1. iii) NRf This is a decimal numeric data type, where NR1 indicates an integer number, NR2 indicates a fixed point real number, and NR3 indicates a floating point real number. iv) Numeric value program data This data type defines numeric values, as well as special cases of Character Data.
MAXimum: sets the parameter to its maximum value. MINimum: sets the parameter to its minimum value. For example, to set the frequency to its maximum value we can send the command FREQ MAX Some Program Message Units either require, or can accept, more than one data element. Program data elements are separated from each other by the Program Data Separator. It is defined as optional white space characters followed by a comma (','), which in turn is followed by optional white space characters.
tells the device to return the minimum or maximum value to which the parameter may currently be set. For example, FREQ? MAX will return the maximum value to which the frequency may currently be set. Not all Program Message units have query forms (for example, SAV), and some Program Message Units might have only the query form (for example IDN?). The instrument puts the response to the query into the output queue, from where it may be read by the controller.
length 10. The error queue is read with the following query: ERR? The first error in the queue is returned, and the queue is advanced. 4.7.2 Error Codes The negative error codes are defined by SCPI. Positive codes are specific to the instrument. The error message is returned in the form ,"" A table of error numbers and their descriptions is presented here.

-223 Too much data. The arbitrary waveform memory limit has been exceeded. -224 Illegal parameter value. The parameter value must be selected from a finite list of possibilities. Device-Specific Errors An error specific to the device occurred. -315 Configuration memory lost. Device memory has been lost. -330 Self-test failed. -350 Queue overflow. Error codes have been lost due to more than 10 errors being reported without being read.
Data were sent before the entire response of a previous query was read. -420 Query UNTERMINATED. An attempt was made to read a response before the complete program message meant to generate that response was sent. Warnings The execution of some commands might cause an undesirable instrument state. The commands are executed, but a warning is issued. 500 510 Trigger rate short Output overload "Trigger rate short" means that the period of the waveform is larger than the value of the internal trigger rate.
