Internal Timebase Verification
Internal Timebase Verification
Verifies output frequency accuracy. All output frequencies are derived from a single generated frequency.
1. Connect a frequency counter to the channel 1 output as shown below (the frequency counter input should be ter-
minated at 50 Ω).
2. Set the instrument to the output described in the table below and measure the output frequency. Be sure the
instrument output is enabled.
Use Waveform Generator
Function Amplitude
Q Sine Wave 1.00 Vpp
* With the optional high-stability OCXO
3. Compare the measured value to the test limits shown in the table.
