Applications and Options
TDMA Power Measurements
 When TDMA methods are employed, e.g. GSM, several users share a frequency channel. Each user is assigned a single timeslot. The FSH's TDMA POWER function performs time-domain power measurements in these timeslots. All the settings required for the GSM and EDGE standards are predefined on the FSH to make these measurements easier for the user. The FSH can use external triggering or video triggering to start power measurements.
Channel-Power Measurements
 The channel-power measurement function is for determining the power in a transmission channel specified by the user. After a few preliminary settings have been made, a single keystroke starts the FSH's spectrum measurement inside the channel, using a resolution bandwidth that is small relative to the channel bandwidth. The FSH then integrates the measured values indicated by the trace to obtain and display the total power. All the settings required for the digital mobile radio standards 3GPP WCDMA, cdmaOne, CDMA2000 1x are predefined ready for use. The FSH also takes the characteristics of the selected display mode (lin or log), the selected detector and the resolution bandwidth into account so that the result accuracy is comparable to that obtained with a thermal power meter.
Power Measurements
 The Power Sensors FSH-Z1 and FSH-Z18 expand the FSH to a high-precision RF power meter up to 8 GHz and 18 GHz respectively. As with thermal sensors, the true RMS value of the measured signal is obtained over the entire measurement range of -67 dBm to +23 dBm irrespective of the signal waveform. In particular with modulated signals, additional measurement errors can thus be prevented, and handling becomes easy.
Measurements on Cables (distance-to-fault)
 For rapid and accurate determination of the distance to any faults in an RF cable. Distance-to-fault measurements using the VSWR Bridge FSH-Z2 give an immediate overview of the state of the device under test (return loss and distance). The marker-zoom function allows detailed analysis of faults with a resolution of up to 1024 pixels.
Requires FSH313/323/626 (with built-in tracking generator), option FSH-B1 (distance-to-fault measurement) and FSH-Z2 (VSWR bridge and power divider).
Scalar Network Analysis
 The FSH313/323/626 (with built-in tracking generator) can be used to determine the transmission characteristics (i.e. attenuation or gain) of two ports such as cables, filters, amplifiers, etc, rapidly and with a minimum of effort. A simple calibration procedure compensates for the attenuation introduced by measurement cables or any attenuators used for amplifier measurements. When the VSWR Bridge FSH-Z2 is attached, the matching (return loss or VSWR) at the input or output of two ports can be determined as well as their transfer function. The bridge is screwed directly onto the RF input and tracking generator output, and no extra or cumbersome cabling is required.
