Refer to the tip cable label for the maximum non-destruct input range when using each tip cable. For example, for direct input to the sensor head using the SMA

nnector this value is ±25 V, but when using the SQPIN100X tip cable the

co value is ±600 V.

As with any analog measurement system, the sensor used in the TIV series has

limited differential input range. If the differential input signal exceeds this

a range, the gain accuracy is reduced.

In the TIV series there are two factors limiting the linear differential voltage range. The ﬁrst is the output voltage range of the ampliﬁer and the sec ond is the linear range of the sensor. If the ampliﬁer output voltage range is exceeded, the signal displayed on the oscilloscope will be clipped. The effects of exceeding the sensor linear range are less apparent and might lead to inaccurate measurements.

This limited linear range results in a reduction in gain that is gradual and might not always be apparent to the user. To obtain the most accurate measurements, the user must take care to maintain the differential input signals within both the ampliﬁer range and the sensor linear range.

For example, if the input signal is a 0 to +1 V triangle wave as shown below, using the 2X Range with no input offset applied will result in a distorted/compressed signal. To make this measurement in this example, the signal should be offset by +500 mV to center it in the most accurate range of the TIV system. In the following ﬁgure, the signal compression is exaggerated for illustrative purposes.

The SQPIN100X tip can be used to measure this signal since this tip has a ±600 V maximum input voltage rating and a linear differential input range of ±50 V (100 V

Advancements in the components used in switching power supplies have made characterizing the performance of these power supplies increasingly difﬁcult and challe high-side V an exceptionally good CMRR is required from the test system, especially for measuring the high-side V circuit.

In this type of circuit, the gate-source voltage is of interest because the rate at which the device switches is determined by the gate drive characteristics. The reference node for this measurement is the high-side source node, which switches

tween the input supply voltage and the local PCB ground during operation. In a

be measurement system without sufﬁcient CMRR, this rapidly changing common mode voltage results in interference which obscures the measurement. It is important to note that the CMRR for all measurement systems is frequency dependent; however, the frequency that is critical for this measurement is not the switching frequency, but the frequency corresponding to the edge rate. For example, to accurately characteriz e a power supply with a switching frequency of 100 kHz and an edge rate of 1 ns, a system with good CMRR at 350 Mhz is necessary because of the edge speed.

the signal is fully resolved and is within the dynamic range of the measurement system.

To get the best CMRR from your TIVH Series IsoVu measurement system, pay careful attention when connecting the measurement system to the DUT. This connection should preserve the signal ﬁdelity and shield the signal from unwanted interfere

nce. To achieve the best performance from the measurement system, use an MMCX connector as close to the test point as possible. The MMCX connectors are available from a number of vendors and are relatively inexpensive. The key attributes of these connectors, which make them excel for this application, are their compact footprint and solid metal body. The solid metal body and gold contacts provide a w ell-shielded signal path.

attenu impedance is used. The common mode resistance is extremely high, greater than G Ω, in parallel with a small capacitance from the tip cable shield to ground, typically 2 pF or less. Keep these impedances in mind when determining how to connect the measurement system to the DUT. The source node in the half bridge circuit is a very low impedance point, and is the point that should be used to

In a typical application, a 0.25 Ω resistor might be used to measure a transient current of 1 A, resulting in a voltage swing of 0.25 V, which can be measured with the measurement system using a 10X tip. A typical surface mount resistor can have a series inductance of less than 0.2 nH and series capacitance of less than

0.04 pF, resulting in much lower impedance at high frequency than could be obtained with a conventional current probe.

Example 4: ESD troubleshooting

Many devices and systems can be negatively affected by ESD discha rges. Troubleshooting problems that occur during an ESD discharge can be very difﬁcult. A piece of test equipment connected to a device undergoing ESD testing has to not only withstand the ESD discharge, but it also has to reject interference caused by the rapid changes in potential on the DUT during an ESD discharge test.

For example, consider using the standard human body model of 100 pF and 1500 Ω. If the DUT is being tested to 4 kV and has a capacitance of 50 pF, the

st equipment will be exposed to a voltage change of more than 1 kV in tens

te of nanoseconds.

The propagation delay will be measured by ﬁrst applying the output of the pulse generator to the input of the o scilloscope and storing the captured waveform as a reference waveform. Next, the measurement system is connected to the oscilloscope and the output of the pulse generator is connected to the input of the measurement system. The delay is then measured between the saved reference waveform and the acquired waveform of the measurement system.
