3. Follow the instructions on the screen and enter the Windows NT Product
Identification number (located above the bar code) on the Windows NT
software package that came with your instrument. Enter other information as
required.
The internal setup software automatically configures your instrument and
installs all required devices. After the setup software completes configura-
tion, the measurement set application will start.
The next time you power on, the application starts automatically. You do not
need to perform step 3 again.
Always power off the instrument using the Windows NT shutdown process and
then press the On/Standby switch.
NOTE
. Once a month, power down and restart the instrument. The measurement
set performs an internal calibration as part of the power on procedure. This
ensures the optimum measurement accuracy of the instrument.
Selecting RF Input Channel and Channel Frequency
Use the following procedure to select the RF Input channel, select the channel
frequency, and verify that the RF input signal has sufficient power. Without
sufficient power at the test signal input, the instrument cannot perform accurate
measurements.
1. Connect your transmitter to one of the RF input connectors shown on
page 1--15 (the connectors are internally terminated in 50
Ω
, so no external
termination is needed).
2. If the input signal strength is more than 1 watt (but no greater than 2 watts),
make sure that the external 10 dB attenuator is installed.
3. Power on the instrument.
4. Click the Setup button on the toolbar.
5. Click on the System tab to display the System page (shown in Figure 1--13).
