Operation and Programming
EXAMPLE 5. FREQUENCY A MEASUREMENT
The following example demonstrates how to display a Frequency A measurement on the display (X register) of •
the HP-41C/CV. Included in the example are the keystrokes required to program the HP-41C/CV.
The following program initializes the counter (locates the counter in the loop and sets the counter to Remade
mode). After initialization, the program sends instructions to measure the frequency at Input A, set up a gate time
of one second, enable the 100kHz low Pass Filter, and send the measurement back to the display of the HP-
41C/CV.
For the example, use the set-up shown in Figure 3-12, Example 5 Set-Up, and make the following adjustments.
1. Set a signal generator to a sine wave frequency of 500 kHz± 10 kHz.
2. Set an output level of 250 mV ± 100 mV.
3. Connect the signal generator to Input A of the HP 5384A/HP 538SA.
4. Cycle the HP 5384A/HP 5385A counter from STBY to ON.
5. Press the INPUT B key.
