    Using a Preamplifi er The R&S FSH has an internal preamplifi er for increasing sensitivity. Depending on the frequency, this amplifi er has 15 dB to 20 dB gain and increases sensitivity by 10 to 15 dB. It is fi tted behind the RF attenuator and in front of the input mixer.
  • Page 78 If the preamplifi er is switched on, its use is coupled to the reference level, thus ensuring the optimum dynamic range of the R&S FSH at all times. The table below shows the positions of the RF attenuator and the preamplifi er as a function of the reference level.

  • Page 79: Measurements On Cw Signals

    Measurements on CW Signals A basic task performed by spectrum analyzers is measuring the level and frequency of sinewave signals. The following examples illustrate the most effective way of performing these measurements with the R&S FSH. A signal generator is used as a signal source, e.g. the Signal Generator R&S SML.
  • Page 80 Press the FREQ key. Enter ‘700’ using the numeric keypad and confi rm the entry with the MHz key. Press the SPAN key. Enter ‘10’ using the numeric keypad and confi rm the entry with the MHz key. The R&S FSH now displays the generator signal with a higher resolution.
  • Page 81 The R&S FSH has markers for reading off signal levels and frequencies. Markers are always positioned on the trace. Both the level and frequency at their current positions are displayed on the screen. Press the marker key. The marker is activated and is automatically positioned on the trace maximum.

  • Page 82: Setting The Reference Level

    3.3.2 Setting the Reference Level The level shown by spectrum analyzers at the top of the measurement diagram is called the reference level (REF LEVEL). To obtain the best dynamic range from a spectrum analyzer, its full level range should be used. This means that the maximum spectrum level should be at or close to the top of the measurement diagram (= reference level).

  • Page 83: Frequency Measurements

    Using markers is also an effective way to shift the trace maximum so that it coincides with the top of the measurement diagram. If the marker is positioned on the trace maximum (as in the example), the reference level can be set to the marker level by entering the following keystrokes: Press the MARKER->...

  • Page 85: Harmonic Measurements Of A Sinewave Signal

    3.3.4 Harmonic Measurements of a Sinewave Signal Since a spectrum analyzer can resolve different signals in the frequency domain, it is ideal for measuring harmonic levels or harmonic ratios. To speed up these operations, the R&S FSH has marker functions that deliver fast results with only a few keystrokes.
  • Page 86 Press the STOP FREQ softkey. Enter '250' using the numeric keypad and confi rm the entry with the MHz key. The R&S FSH now displays the spectrum from 50 MHz to 250 MHz and thus the signal at 100 MHz and its second harmonic at 200 MHz.

  • Page 87: Power Measurements Using The Power Sensor

    Power Measurements Using the Power Sensor For highly accurate power measurements, the R&S FSH provides the Power Sensor R&S FSH-Z1 or R&S FSH-Z18 as options. They measure power in the span 10 MHz to 8 GHz or 10 MHz to 18 GHz, respectively.
  • Page 88 Risk of damage to the sensor due to high input power • The continuous power applied to the power sensor’s input must not exceed 400 mW (26 dBm). • Use an attenuator for measurements on high- power transmitters. However, brief (≤10 µs) power peaks up to 1 W (30 dBm) are permissible.
  • Page 89 The R&S FSH changes to power measurement mode and opens the screen for the power measurement. If a power sensor has not been connected, no measured value is displayed. If a power sensor has been connected, the R&S FSH sets up a connection via the interface and, after a few seconds, displays the measured power.
  • Page 90 The R&S FSH immediately starts power meter zeroing. While this process is being performed, the R&S FSH outputs the message “Zeroing power sensor, please wait... ” . When zeroing is over, the R&S FSH outputs the message „Power Sensor Zero OK“ and switches back to the softkey menu for the power sensor.
  • Page 91 For a highly accurate measurement, enter the frequency of the signal under test. Press the FREQ softkey. Using the numeric keys, enter the frequency you want and confi rm the entry with the ENTER key or by pressing the FREQ softkey again. The R&S FSH transfers the new frequency to the power sensor which then corrects the measured power readings.

    Power and Return Loss Measurements with the R&S FSH-Z14 or the R&S FSH-Z44 The Directional Power Sensors R&S FSH-Z14 and R&S FSH-Z44 are connected between the source and the load and measure the power fl ux in both directions, i.e. from the source to the load (forward power) and from the load to the source (reverse power).
  • Page 93 When measuring high powers, pay strict attention to the following instructions to avoid personal injury and to prevent the power sensor from being destroyed: Danger of skin burns and damage to the instrument • Never exceed the permissible continuous power. •...
  • Page 94 Before performing the power measurement, zero the power sensor. Press the ZERO softkey. The R&S FSH informs you not to apply any signals while the power sensor is being zeroed. Disconnect the power sensor from any signal sources. Start zeroing with the CONTINUE softkey. The softkey CANCEL can be used to cancel zeroing before it begins, e.g.
  • Page 95 When zeroing is over, the R&S FSH outputs the message “Power Sensor Zero OK” and switches back to the softkey menu for the power sensor. Now connect the R&S FSH-Z14 or R&S FSH-Z44 between the source and the load. The R&S FSH displays the measured forward power level in dBm and the VSWR of the load.

    After the calibration is fi nished, the R&S FSH displays TRANSM. SCALAR (NORM) at the top. 3.6.3 Measure the magnitude of the transfer function After a two-port calibration it is possible to switch between forward and reverse without having to recalibrate the R&S FSH anew.
  • Page 101 The calibration for the transmission measurement is not lost if the start, stop frequency, the center frequency and the span are subsequently changed within the calibrated frequency domain. In this case, the R&S FSH interpolates the correction data between the reference points of the calibration. In this case, the R&S FSH displays (Approx) at top left and indicates the possibly increased measurement error.

    Return Loss Measurement (For R&S FSH models with a tracking generator and a built-in VSWR bridge only, order no. 1309.6000.24 or 1309.6000.28) The R&S FSH-Z28 (0 GHz to 8 GHz) or R&S FSH-Z29 (0 GHz to 3.6 GHz) calibration standard is required for measuring the return loss.
  • Page 103 For measurements on devices under test which require an external voltage supply (e.g. power amplifi ers), connect the supply voltage from a suitable AC power supply to the appropriate BIAS PORT 1 or BIAS PORT 2 input. The test setup must be calibrated prior to the measurement.

Select the DTF ONLY menu item with the rotary knob or the cursor keys (∧ or ∨) and confi rm the selection with the ENTER key or the CALIBRATE softkey. The R&S FSH opens a text window that prompts you to terminate the measurement cable with a SHORT.
  • Page 114 Remove the SHORT from the measurement cable. Screw the cable under test to the measurement cable. The R&S FSH displays the return loss produced in the cable under test versus the distance. Checking the spectrum in the span for detecting external interferers Press the MEAS MODE softkey.
  • Page 115 Additional measurement of the impedance matching: Apart from the DTF measurement, the R&S FSH offers the option of also determining the cable impedance matching as a function of the frequency. For this purpose, the R&S FSH must be calibrated with three calibration standards (short- circuit, open circuit and 50 ohm match) instead of with just one.
  • Page 116 With the REFLECTION setting, the R&S FSH changes from the DTF measurement to measuring the impedance matching and displays this via the frequency. As an indication that the R&S FSH is working in refl ection display mode, it displays DTF REFLECTION at the top of the screen. Otherwise, the R&S FSH uses exactly the same settings as it did for DTF measurements.
