Data Sheet

LXI Class-C-Compliant Power Meter

A P-Series power meter is a LXI Class-C-compliant instrument, developed using LXI Technology. LXI, an acronym for LAN eXtension for Instrumentation, is an instrument standard for devices that use the Ethernet (LAN) as their primary communication interface.

Hence, it is an easy-to-use instrument especially with the usage of an integrated Web browser that provides a convenient way to configure the instrument’s functionality.

Specification definitions

There are two types of product specifications:

• Warranted specifications are specifications which are covered by the product warranty and apply over a range of 0 to 55 ºC unless otherwise noted. Warranted specifications include measurement uncertainty calculated with a 95 % confidence.

Characteristic information is representative of the product. In many cases, it may also be supplemental to a warranted specification. Characteristic specifications are not verified on all units. There are several types of characteristic specifications. They can be divided into two groups:

One group of characteristic types describes ‘attributes’ common to all products of a given model or option. Examples of characteristics that describe ‘attributes’ are the product weight and ‘50-ohm input Type-N connector’. In these examples, product weight is an ‘approximate’ value and a 50-ohm input is ‘nominal’.

8.5 inch

These two terms are most widely used when describing a product’s ‘attributes’.

Conditions

The power meter and sensor will meet its specifications when:

• stored for a minimum of two hours at a stable temperature within the operating temperature range, and turned on for at least 30 minutes

• the power meter and sensor are within their recommended calibration period, and

• used in accordance to the information provided in the User’s Guide.

13.7 inch

3.5 inch

• Characteristic specifications are specifications that are not warranted. They describe product performance that is useful in the application of the product. These characteristic specifications are

Signal under test rise time (nS)

Figure 1. Measured rise time percentage error versus signal under test rise time

Although the rise time specification is ≤ 13 ns, this does not mean that the P-Series meter and sensor combination can accurately measure a signal with a known rise time of 13 ns. The measured rise time is the root sum of the squares (RSS) of the signal under test rise time and the system rise time (13 ns):

Measured rise time = √((signal under test rise time)3 + (system rise time)3)

and the % error is:

% Error = ((measured rise time – signal under test rise time)/signal under test rise time) x 100

System specifications and characteristics

The video bandwidth in the meter can be set to High, Medium, Low and Off. The video bandwidths stated in the table below are not the 3 dB bandwidths, as the video bandwidths are corrected for optimal flatness (except the Off filter). Refer to Figure 2 for information on the flatness response. The Off video bandwidth setting provides the warranted rise time and fall time specification and is the recommended setting for minimizing overshoot on pulse signals.

Recorder output and video output

The recorder output is used to output the corresponding voltage for the measurement a user sets on the Upper/Lower window of the power meter.

The video output is the direct signal output detected by the sensor diode, with no correction applied. The video output provides a DC voltage proportional to the measured input power through a BNC connector on the rear panel. The DC voltage can be displayed on an oscilloscope for time measurement. This option replaces the recorder output on the rear panel. The video output impedance is 50 ohm.

Characteristic Peak Flatness

The peak flatness is the flatness of a peak-to-average ratio measurement for various tone separations for an equal magnitude two-tone RF input. Figure 2 refers to the relative error in peak-to-average ratio measurements as the tone separation is varied. The measurements were performed at –10dBm with power sensors with 1.5m cable lengths.

Effect of video bandwidth setting

The noise per sample is reduced by applying the meter video bandwidth filter setting (High, Medium or Low). If averaging is implemented, this will dominate any effect of changing the video bandwidth.

Effect of time-gating on measurement noise

The measurement noise on a time-gated measurement will depend on the time gate length. 100 averages are carried out every 1 μs of gate length. The Noise-per-Sample contribution in this mode can approximately be reduced by √(gate length/10 ns) to a limit of 50 nW.
