Our business revolves around RF power measurements; we receive and answer many questions. Below is a compilation of questions that are often asked. Please contact us if you would like to discuss your application or have any specific questions. Click to expand the question.
I am measuring an OFDM signal and the power reading is jumping from -66 dBm to 13 dBm. How can I measure this signal correctly?
Turn on the anti-aliasing filter and increase averaging until the readings stabilize. This will help ensure a complete capture of a slow moving signal.
Yes. Turn on the anti-aliasing filter and increase averaging until the readings stabilize. When using the LB478A, LB479A or LB480A, keep in mind signal accuracy will degrade as signal content beyond 10 MHz increases.
Yes. Any of our True RMS sensors LB559A, LB579A, LB589A and LB5900 series sensors will accurately measure average power on signals with any modulation content. When using the LB478A, LB479A or LB480A depending on signal content accuracy can degrade. Turn on the anti-aliasing filter. If the signal is bursty or slow moving you may want to increase averaging until the readings stabilize. These steps ensure complete capture of slow moving signals and eliminate aliasing associated with high frequency content.
I am having trouble getting a stable measurement in the power meter application. What is wrong and what can I do?
This can happen for several reasons. One reason might be that you have a signal with a low PRF and very narrow pulses. Another reason might be that you have a slow moving signal. In both these cases we recommend increasing the averaging and turning on the anti-aliasing filter.
Yes. All of our instruments are calibrated and traceable to NIST.

Our Power Sensors carry a three (3) year return to factory Defects in Materials and Workmanship Warranty. Abuse and overpowering are specifically excluded. Simply contact us for an RMA Number, then send the sensor in prepaid for evaluation and we contact you. Sensors repaired under warranty will be returned (US Address Only) by prepaid ground shipping. Note that calibration assurance is separate from the warranty, LadyBug provides a 1 year certificate of calibration with each sensor; refer to extended calibration services for more information. More information
The answer is yes and no. In general the warranty covers only repair. However, during the warranty period, any instrument we service will also be calibrated, if it is also within the calibration period, a new certificate will also be generated. Please refer to the extended calibration plan for further information.
A sensor receives its initial one year calibration when it ships new, if extend calibration is purchased, two additional calibrations are provided giving the user 3 total years:
• One at the end of the first year
• One at the end of the second year
Repair is not included, however if a sensor is repaired while in the calibration period it will be calibrated and a certificate issued for the remainder of the calibration period.
