4. To begin with lets explore the panel controls to see how they feel react and what they do All other panels share almost the same feel so the description of how to operate the Main Panel can serve as general guide for controlling the rest of the panels Looking at the panel you can identify the following controls Push User Manual TE5200 buttons LED s radio buttons Dial and Digital display The function of each control is described below Push Buttons These are used for two functions a For selecting an active parameter and b for toggling a function on and off For example the button in the Parameters group will select between the Amplitude and Offset LED s The selection buttons have momentary push action so pressing clicking a mouse on this button will change the reading on the display to correspond with the selected parameter The State button in the Output group has toggles the output on and off The first mouse click will push the button inwards and will turn on a red bar at the center of the button indicating that the function is on The second mouse click will turn the function off Radio Buttons Are used for changing operating modes or selecting between mode options One of the radio buttons is always on with a red dot in its center indicating its state condition Pressing some radio buttons will pop up a new panel For example if you press the Triggered button in the operating Mode group triggered oper
5. Wait for all pending operations to complete before executing any additional commands over the interface The Model TE5200 uses the Status Byte register group and the Standard Event register group to record various instrument conditions Figure 4 1 shows the SCPI status system An Event Register is a read only register that reports defined conditions within the generator Bits in an event register are latched When an event bit is set subsequent state changes are ignored Bits in an event register are automatically cleared by a query of that register or by sending the CLS command The RST command or device clear does not clear bits in an event register Querying an event register returns a decimal value which corresponds to the binary weighted sum of all bits set in the register An Event Register defines which bits in the corresponding event register are logically ORed together to form a single summary bit The Programming Reference 4 62 User Manual TE5200 The Status Byte Register STB user can read from and write to an Enable Register Querying an Enable Register will not clear it The CLS command does not clear Enable Registers but it does clear bits in the event registers To enable bits in an enable register write a decimal value that corresponds to the binary weighted sum of the bits required to enable in the register The Status Byte summary register contains conditions from the other registers Query data waiting in

7. Note Normal color of the digital reading is dark blue If you modify the reading the color changes to a lighter shade of blue indicating that the TE5200 has not been updated yet with the new parameter Pressing Execute will update the instrument and will restore the color of the digital readout to dark blue indicating that the displayed value is the same as the generator setting Also note that the digital readout has an autodetect mechanism for the high and low limits You cannot exceed the limits if you are using the dial but only if you use the keypad In case you do the program will not let you download an illegal parameter and you ll be requested to correct your setting ArbConnection 3 13 User Manual TE5200 Figure 3 5 The Arbitrary amp Sequence Panel Sample Clock The Sample Clock group is comprised of one parameter that controls the sample clock frequency Note that the sample clock rate is programmed in units of S s samples per second and will affect the Model TE5200 only when it is programmed to output arbitrary or sequenced waveforms To access the required parameter click on the button until the LED next to the required parameter turns on The value that is associated with the lit LED is displayed on the digital display You can use the dial keyboard or the T LU keys to adjust the readout to the required setting After you modify the reading press Execute to update the TE5200 with the new reading

10. Synchronizing The capability to synchronize multiple instruments is one of the strongest F features of the Model TE5200 However since each instrument is free running Multiple and has completely independent settings and controls one must first prepare Instruments the instruments to a level where all instruments can unite There are some simple steps to synchronize instruments however three conditions must be met otherwise synchronization will fail they are 1 Synchronized cards must be adjacent to each other and 2 Master module must be at the left of the clustered instruments 3 The module which is at the far right side of the cluster is designate as Last slave NOTE Every cluster of synchronized instruments must have one master and one last slave The master module is always at the left side of the cluster and the last slave is always at the far right side of the cluster Any number from 0 to n modules can be placed between the master and the slave modules Programming Reference 4 47 User Manual TE5200 After you have your master and slave units in place you ll have to execute a series of commands to prepare the instruments to their final lock position The following example assumes three adjacent instruments As was explained before the left instrument is called master the center instrument is called slave and the instrument on the right is called last slave Here is what you do Program
