> Term Count a terminal sample count. Use any of the data entry controls to enter a terminal count in
Megasamples. Limits 2.0 M to 4096.0 M Megasamples.
Note If both total sample count and running time terminal conditions are set, the first terminal condition met will
control the process.

EXERCISE
MEAS
Press the MEAS function key, and perform the following exercises to become
familiar with frequency entry.
The instrument will automatically read the frequency correction data from the sensor and apply
the correction to the measurement.
Because the sensor is connected to the calibrator output for these exercises, the
measurement frequency must be set to 1.0 GHz (the frequency of the calibrator signal) to obtain a
valid reading.
Meas > Freq Track This selection turns frequency tracking On and Off. Frequency tracking ―On‖
links both channels together with the same frequency. The ―Off‖ setting allows the channels to be
set to different frequencies.
Meas > Freq CH1
Use any of the data entry controls to select the measurement frequency for
CH 1. This frequency selection is used to calculate the required correction factor.
The data can be entered in Hz, kHz, MHz or GHz, however, the frequency must lie within the
range of the CH 1 sensor in use. If a value outside this range is entered, the nearest limit frequency
will actually be entered and displayed, and no error will result. The frequency limits may be
different for the sensor‘s high and low bandwidth ranges. You can find the frequency range limits
for the sensor in use by pressing the Spcl > Sensor Data > CH 1 Sensor> Report menu key. If a
frequency becomes illegal because of a bandwidth change, it will be forced to the nearest limit
frequency. The frequency resolution is 0.01 GHz (10 MHz).
