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.

Function Amplitude Frequency Nominal Error*
Q Sine Wave 1.00 Vpp 10.000,000,0 MHz 10.000 Mhz ± 10 Hz
* With the optional high-stability OCXO timebase, the measurement error is ±1 Hz
3. Compare the measured value to the test limits shown in the table.
