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.
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.
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.
