4.4.2.2 Frequency Range, Resolution & Accuracy
4.4.2.2.1 Description
Connect the 2400 RF output to the input of a frequency counter. The internal timebase of the counter
is used as a reference for the 2400 to eliminate timebase errors from the measurements. This proce-
dure does not check for timebase accuracy.
4.4.2.2.2 Equipment Required
• UUT
• Frequency Counter
• Coaxial Cable

4.4.2.2.1 Procedure
1. Connect the equipment as shown in Figure 4-1. Connect the 2400 RF Output to the 10 to 500
MHz counter input using the coaxial cable and the SMA to BNC adapter. Allow the equipment to
warm up for at least 30 minutes. Because the 2400 and the counter use the same timebase, time-
base errors are eliminated. The 2400 will automatically switch to the external reference when it is
connected.
2. Set the 2400 to 10 MHz. Press [LEVEL] in the POWER field and enter [+] [0] [DBM]. Press the [RF
ON] button to activate the 2400 output.
