Sweep Setup

4.5.

Sweep refers to the measuring process of continuous data points with stimulus values in specified sequence.

www.salukitec.com

4.5.1.

The Analyzer supports five types of sweep as follows:

 Linear frequency

This is the default sweep type for Analyzer. The frequency intervals between two neighbor measuring points are equal.

 Logarithmic frequency

Under the setting of logarithmic frequency, source frequency increases in logarithmic step size and frequency ratios between two
neighboring measuring points are the same.

 Power sweep

Power sweep is adopted for power-sensitive parameters, such as gain compression or AGC (automatic gain control) slope. Power
sweep is conducted in CW Time. The maximum vailable sweep range is 25dB and the default power sweep range is

-15dBm~+10dBm. During sweep, the power is swept with scattered step value from start value to end value and the step size is
decided by Sweep spot number and power range.

 CW Time

For this sweep type, Analyzer is set to single sweep frequency. The measuring data is sampled continuously and precisely in time
interval decided by Sweep time and measuring points, showing the change of measuring data over time.

 Segment sweep

Sweep type

This sweep type is made up with several segments, each of which can be defined with independent power level, IF bandwidth and
Sweep time. When calibrations are completed for all segments, Measures can be conducted for one or more segments. The
segments are defined in the sequence of frequency increase and the frequency range cannot overlap. The attenuator setting for
power level of all segments must be the same so as to prevent the attenuator from being damaged by frequent switching of
attenuator. When the attenuator setting for current defined segment is different from that for defined segment, Analyzer will
automatically change the power level and attenuator setting of defined segment.

Trigger source settings determine where the trigger signal is from. Effective trigger signal will yield only when the Analyzer is not
Sweep. The Analyzer may select 3 types of trigger source: internal, manual and external. Once the trigger source is set, the Analyzer
will apply this trigger source to all channels.

 [Internal] (default)

 The Analyzer will automatically control the generation of trigger signal.

 The Analyzer will generate a trigger signal immediately after a Measure.

 [Manual]

 Manual trigger signal may be created by the following averages:

 Click [Manual Trigger] in Trigger dialog box.

 Press the Trigger key in front panel and press the corresponding soft-key to [Manual Trigger] in soft-key toolbar.

 Call program control command.

 [External]

 Trigger signal is input from external trigger input connector on the rear panel.

 The signal is TTL level.

 Level trigger, active level (high active or low active) is set via External Trigger dialog box.

 Pulse width shall be at least 1us but not longer than Sweep time (several triggers may be aroused when pulse width

is longer than Sweep time).

 Trigger Scope zone

Trigger range settings determine what Measure channels of Analyzer will receive trigger signal. There are two settings for trigger
range: All and Channel:

 [All]

This is the default setting for Analyzer. All the other channels will receive trigger signal except for the channel in Hold mode.

 [Channel]

Only the next channel not in Hold mode will receive trigger signal. When Measure is completed for the current channel, Analyzer will

select automatically the next channel to receive trigger signal. All the other channels will be selected in order except for the channel

in Hold mode. This setting has no evident influence on Measure unless Trigger Source is set to be manual status. When Channel

setting is selected, spot sweep function will be available.

 Channel Trigger State zone

Trigger settings determine how many trigger signals will be received by one channel. There are four channel trigger status:

 [Continuous]

The channel will receive unlimited trigger signals and continue to sweep.

 [Group]

The channel will receive the trigger signal with the number specified in [Group] input box to conduct Sweep for specified times and
then enter into Hold mode.

 [Single]

The channel will receive one trigger signal to conduct one Sweep, and then enter into Hold mode.

 [Hold]

The channel will not receive trigger signal and stop Sweep.

 [Channel Selection]

Select the channel adaptable to trigger settings.

 [Spot Sweep]

This trigger mode can be selected only when trigger source is manual or external and trigger range is channel. Under spot sweep
mode, when the channel receives trigger signal, the next data point in the Sweep will be measured. The channel will receive trigger
signal until all Measures in the channel are complete, and then it will trigger the next channel not in Hold mode.

Selecting Data Format and Scale

4.7.

Data format refers to the way the Analyzer graphically displays Measure data. The data format most suitable for understanding the
property of measured piece shall be selected during the Measure. This section introduces 9 data formats and how to set the scale so
as to better display measuring information.

4.7.1. Data Format

4.7.1.1. Rectilinear coordinate format

7 among the 9 data formats display measuring data information in rectilinear coordinate, which is also called Descartes format, X/Y
format or linear grid format. This is most suitable for displaying frequency response information of the measured piece. Rectilinear
coordinate will display the following information:

 By default, X axis displays stimulus value in linear scale (frequency, power or time).

 Y axis displays the corresponding response value at different stimulus values.

Fig. 4-23 Rectilinear Coordinate Format

The 7 data formats displayed in rectilinear coordinate are:

 Log-magnitude format

 Display magnitude information (without phase information).

 Y axis unit: the unit is dB when ratio is measured and it is dBm when non-ratio power is measured.

 Suitable typical Measure: return loss, insertion loss and gain.

 Phase format

 Display phase information (without magnitude information).

 Y axis unit: phase (degree).

 Suitable typical Measure: linear phase deviation.

 Group delay format

 Display the transfer time of signal passing through the measured piece.

58

Tel: [phone] Email: [email protected]

 Y axis unit: time (second).

 Suitable typical Measure: group delay.

 Linear magnitude format

 Only positive value will be displayed.

 Y axis: no unit (U) when ratio is measured and the unit is watt (W) when non-ratio power is measured.

 Suitable typical Measure: reflectance and transfer factor (magnitude value), time domain transformation.

 SWR format

 It display reflection Measure data through the formula:(1+ρ)/(1-ρ), in which ρ is the reflectance.

 It is effective only reflection Measure is conducted.

 Y axis: no unit.

 Suitable typical Measure: standing wave ratio format.

 Real format

www.salukitec.com

 Display the real part of measuring complex data.

 Similar with linear magnitude format, but may display positive and negative value.

 Y axis: no unit.

 Suitable typical Measure: time domain Measure, auxiliary input voltage signal Measure for maintenance purpose.

 Imaginary format

 Display the imaginary part of measuring complex data only.

 Y axis: no unit.

 Suitable typical Measure: impedance Measure when matching network is designed.

4.7.1.2.

Polar coordinate format

Polar coordinate format includes magnitude and phase information, and the vector value is read by the following averages:

 The magnitude for any point is determined by the displacement from this point to the center point (or zero point). By default, the

magnitude is in linear scale and the outer circle is set to be at the ratio 1.

 The phase value of any point is determined by its included angle to X axis.

 As there is no frequency information, frequency information is read through marker. By default, the marker format is

real/imaginary part. The other formats may be selected through the Marker dialog box in Marker menu.

4.7.1.3. Smith Chart format

Smith Chart is a tool for mapping the reflection Measure data of the measured piece to impedance. Each point on the chart
represents one complex impedance made up of real resistance (R) and virtual reactance (±jX). The resistance value, reactance
value and reactance equivalent capacitance or inductance of the measured piece may be read through the marker.

Fig. 4-25 Smith Chart Format

 The central horizontal axis of Smith Chart represents pure resistance, and the center point of horizontal axis represents system

impedance; the far left resistance is zero which represents short circuit; the far right resistance of horizontal axis is infinite which
represents enabled circuit.

 On the chart, the points on the circle intersecting with horizontal axis have the same resistance value.

 On the chart, the points on the circle (or arc) tangent with horizontal axis have the same resistance value.

 On the chart, the reactance of the upper part is positive, therefore it's inductive zone; the reactance of the lower part is negative,

therefore it’s capacitive zone.

6.4.Bandwidth Test

Bandwidth test function is mainly applied to test the bandwidth of band-pass filter.

Bandwidth test can find out signal peak value in the pass band and locate two points on specified amplitude on the two sides of the
pass band. The amplitude is lower than the signal peak value and can be adjusted through setting N dB point (default value is 3 dB).
The frequency range between the two points is the bandwidth of the filter under test.

Bandwidth test can set the minimum bandwidth and maximum bandwidth that the users allow before testing and the tested
bandwidth will compare automatically with the two values. If the result is not satisfactory, the users will see the fail information on the
screen or hear the sound hint, which are convenient for the the users to see if the characteristics of the device under test can meet
the requirement.
