Getting Started 3-28
MENU ITEM EXERCISE
MEAS (continued)
Meas > Freq CH1
Use any of the data entry controls to select the measurement frequency for
CH 1. This frequency selection is used to calculate the required correction factor.
The data can be entered in Hz, kHz, MHz or GHz, however, the frequency must lie within the
range of the CH 1 sensor in use. If a value outside this range is entered, the nearest limit frequency
will actually be entered and displayed, and no error will result. The frequency limits may be
different for the sensor‘s high and low bandwidth ranges. You can find the frequency range limits
for the sensor in use by pressing the Spcl > Sensor Data > CH 1 Sensor> Report menu key. If a
frequency becomes illegal because of a bandwidth change, it will be forced to the nearest limit
frequency. The frequency resolution is 0.01 GHz (10 MHz).
Meas > Freq CH2
Frequency entry for Channel 2 (if installed) operation. The procedure is the same as for Channel 1
discussed above.
Meas > Sys Tracking
When System Tracking is ―On‖, the following channel parameters are linked together such that
changing the value in any channel changes the parameter value in all of the linked channels. An
asterisk ―*‖ appears in the menu title of linked parameters. The parameters are: Units, Peak Hold,
Video BW, Averaging, Distal, Mesial, Proximal, Pulse Units Start Gate, End Gate.
Note The Model 4500B readings are always full scale, so data is not lost when vertical settings are changed.
Thus, there is no danger of losing data related to events that occur during adjustment of Vertical Scale,
Vertical Center, dB Offset, Freq CF or Frequency.
This concludes the Practice Pulse Power Exercises. Press the INIT function key to clear the practice parameter
settings and the instrument will be ready to use.
Hint For best results, read the rest of this Instruction Manual through Section 6, APPLICATION NOTES,
Before using the Model 4500B to make operational measurements.
