Procedures Optimizing Readings
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 6-19
CAL F = frequency cal factors using factory defined table
CAL V = volts per GHz cal factors using factory defined table
CAL M = manual cal factor
CAL *F = frequency cal factors employing a user defined table
CAL *V = volts per GHz cal factors employing a user defined table
This is because the application of user cal factors can completely change the calibrated
response of the Sensor.
6-14 Optimizing Readings
This section presents information on how to get the fastest readings from the ML243xA
Power Meter when operating under GPIB control. Refer to Chapter 6, GPIB Operation, for
specific command descriptions.
Measurement speed depends greatly on the type of measurements being taken, the power
level, and the amount of settling used.
Using the default system set up (system preset), the “O 1” command is used to retrieve one
reading from channel 1 ten times (channel 1 = Sensor A).
Note
All results shown in this section are from DOS programs running on a 200 MHz
controller using IEEE 488.2 GPIB function calls. The timings (readings/second)
presented in this section are for illustrative purposes only.
