2 Operating Your Frequency Counter
66 Keysight 53150A/151A/152A Operating Guide
Summary of the Measurement Sequence
1 Turn on the Main ~ Power switch on the back panel, and then press and
release the POWER button on the front panel.
2 Connect the input signal to the appropriate input connector (Channel 1 or
Channel 2).
3 Connect an external reference signal to the External Reference connector on
the back panel (if desired).
4 Press the Chan Select key to select the input channel (if necessary).
5 Press the Display Power key if you need to measure power (Channel 2 only).
6 Press the frequency and/or power Offset On/Off keys to enable offset
measurements (if desired), and then use the Freq Offset (Shift + Rate) and/or
Pwr Offset (Shift + Avg) keys to enter the offset values.
7 Use the Resol, Rate, and Avg keys to configure the display.
8 Use the Menu (Shift + Reset/Local) key to set the reference-oscillator source,
to select the Channel 1 low-pass filter, to configure the Counter’s response to
frequency modulation, to enable and configure Power Correction, and/or to
select a previously saved set of user settings.
9 If you intend to operate the counter remotely using the GPIB, use the GPIB
(Shift + Resol) key to configure the GPIB.
10 If you intend to operate the counter remotely using the serial interface, use
the Menu (Shift + Reset/Local) key to adjust the serial port Baud rate.
NOTE
The internal Reference Oscillator receives power only when the
Main ~ Power switch is on. Therefore, the frequency of the reference signal may
drift until the oscillator stabilizes. Specifications for the stability of the standard
internal timebase and the optional Oven Timebase are provided in Chapter 3.
