Patent ID: 7595792

Claim:
A measuring device comprising: a plurality of functional units having adjustment parameters that can be adjusted; a control device configured to control adjustment of the adjustment parameters using corresponding operating elements; and a display device configured to display the plurality of functional units as functional blocks having the operating elements, wherein the display device is configured to depict connectivity of the plurality of functional units by depicting corresponding connectivity of the plurality of functional blocks, the display device being configured to display a dialog window of a selected functional block in a foreground of the display of the plurality of functional blocks, wherein the dialog window includes operating elements that can be used to adjust the adjustment parameters of the selected functional block, wherein the control device can be manipulated to highlight a plurality of the operating elements on the display device, wherein the control device is configured to switch on a value editor for each of the highlighted plurality of the operating elements, and wherein the control device has at least two edit modes configured to enter a change to alphanumeric values of the highlighted plurality of the operating elements in order to adjust corresponding adjustment parameters, wherein a first edit mode of the at least two edit modes is configured to allow for adjustment of the alphanumeric values using a most recently adjusted alphanumeric value as a starting value and adjusting the starting value, wherein the first edit mode comprises a first variation function and a second variation function, and both variation functions can be opened alternately by activating a switching key, wherein the switching key is separate from controls used to adjust the first variation function and the second variation function, wherein a second edit mode of the at least two edit modes is configured to allow for adjustment of the alphanumeric values by directly entering alphanumeric values using a keypad, and wherein the plurality of functional units includes baseband units configured to generate baseband signals, fading units configured to apply fading to the baseband signals, noise units configured to apply a noise signal to the baseband signals, and I/Q modulators configured to receive the baseband signals from the noise units, high-frequency units connected to the I/Q modulators and configured to send a high-frequency signal to a device under test, a signal display configured to monitor the baseband signals at various locations via switching elements, and a bit error rate tester configured to receive a signal from the device under test.
