These specifications apply to the PXIe-6570. When using the PXIe-6570 in the Semiconductor Test System, refer to the Semiconductor Test System Specifications.

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty. Warranted specifications account for measurement uncertainties, temperature drift, and aging. Warranted specifications are ensured by design or verified during production and calibration.

The following characteristic specifications describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

Typical specifications describe the performance met by a majority of models.
Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Nominal unless otherwise noted.

Conditions

Specifications are valid under the following conditions unless otherwise noted.

Operating temperature of 0 °C to 45 °C
Operating temperature within ±5 ºC of the last self-calibration temperature
Recommended calibration interval of 1 year. The PXIe-6570 will not meet specifications unless operated within the recommended calibration interval.
DUT Ground Sense (DGS) same potential as the Ground (GND) pins
Note
The DGS feature is only available on PXIe-6570 module revisions 158234C-xxL or later.
Chassis fans set to the highest setting if the PXI Express chassis has multiple fan speed settings
30-minute warmup time before operation

Note

When the pin electronics on the PXIe-6570 are in the disconnect state, some I/O protection and sensing circuitry remain connected. Do not subject the PXIe-6570 to voltages beyond the supported measurement range.

Figure 3. Warranted Current Accuracy Zone for PPMU Force Current

Note

The boundaries of Zone 1 are inclusive of that zone. The area outside of Zone 1 does not have a warranted spec for PPMU force current accuracy.

How to Calculate PPMU Force Current Accuracy

Specify the desired forced current.
Based on the desired forced current, select an appropriate current range from Table 1.
Divide the desired forced current from step 1 by the current range from step 2 and multiply by 100 to calculate the Percent of Current Range Forced.
Based on the impedance of the load, calculate the voltage required to force the desired current from step 1. Use the following equation: Voltage Required = Desired Current * Load Impedance.
Using Figure 2, locate the zone in which the Percent of Current Range Forced calculated in step 3 intersects with the Voltage calculated in step 4. If the intersection is outside of Zone 1, then there are no warranted specs. To get warranted specs, the current range and/or forced current must be adjusted until the intersection is in Zone 1.
Based on the zone found in step 5, use Table 1 to calculate the accuracy of the forced current.

±32 mA	7.3 μA

Figure 4. Warranted Current Accuracy Zones for PPMU Measure Current

Note

The boundaries of Zone 1 are inclusive of that zone. All other boundaries are inclusive of Zone 2. The area outside of Zone 1 and Zone 2 does not have a warranted spec for PPMU measure current accuracy.

How to Calculate PPMU Measure Current Accuracy

Specify the desired measured current.
Based on the desired measured current, select an appropriate current range from Table 2.
Divide the desired measured current from step 1 by the current range from step 2 and multiply by 100 to calculate the Percent of Current Range Measured.
If forcing voltage and then measuring current, Voltage in Figure 3 is equal to the forced voltage. If forcing current and then measuring current, Voltage in Figure 3 is equal to the voltage required to force the desired current based on the impedance of the load. Use the following equation: Voltage Required = Desired Current * Load Impedance.
Using Figure 3, locate the zone in which the Percent of Current Range Measured calculated in step 3 intersects with the Voltage calculated in step 4. If the intersection is outside of Zone 1 or Zone 2, then there are no warranted specs. To get warranted specs, the current range and forced current or forced voltage must be adjusted until the intersection is in Zone 1 or Zone 2.
Based on the zone found in step 5, use Table 2 to calculate the accuracy of the measured current.

Calculating Frequency Counter Error

Use the following equation to calculate the frequency counter error (ppm).

(\frac{{T B}_{e r r}}{(1 - {T B}_{e r r})} + \frac{20 n s}{(M e a s u r e m e n t T i m e - U n k n o w n C l o c k P e r i o d)}) * 1, 000, 000

where

MeasurementTime is the time, in seconds, over which the frequency counter measurement is configured to run
UnknownClockPeriod is the time, in seconds, of the period of the signal being measured
TB_err is the error of the Clk100 timebase

Refer to the following table for a few examples of common Clk100 timebase accuracies.

Table 3. TB_err

PXI Express Hardware Specification Revision 1.0	PXIe-1085 Chassis	PXIe-6674T Override
100 µ (100 ppm)	25 µ (25 ppm)	80 n (80 ppb)

Example 1: Calculating Error with a PXIe-1085 Chassis

Calculate the error of performing a frequency measurement of a 10 MHz clock (100 ns period) with a 1 ms measurement time using the PXIe-Clk100 provided by the PXIe-1085 chassis as the timebase.

Solution

(\frac{25 µ}{(1 - 25 µ)} + \frac{20 n s}{(1 m s - 100 n s}) * 1, 000, 000

$= 45 p p m$

Example 2: Calculating Error when Overriding with the PXIe-6674T

Calculate the error if you override the PXIe-Clk100 timebase with the PXIe-6674T and increase the measurement time to 10 ms.

Solution

(\frac{80 n}{(1 - 80 n)} + \frac{20 n s}{(10 m s - 100 n s}) * 1, 000, 000

$= 2 p p m$

¹ The system channel count is the maximum number of channels available when using multiple PXIe-6570 instruments in a single chassis as a digital subsystem. Some functionality described in this document requires that a PXIe-6674T synchronization module be used in conjunction with each digital subsystem.
² If the total voltage sourced or driven on any pin relative to GND exceeds the supported measurement range, instrument performance may be degraded.
³ Voltages > 6 V require the Extended Voltage Range mode of operation.
⁴ Sourced from chassis 100 MHz backplane reference clock, external 10 MHz reference, or PXIe-6674T.
⁵ When using NI-Digital 18.0 and later, the maximum vector rate for patterns may be limited by the pulse width requirements, which may not allow all formats and edge multipliers to be used up to the fastest vector rate.
⁶ The SBC format is not supported within the 2x edge multiplier mode.
⁷ This functionality requires NI-Digital 18.0 or later.
⁸ 31 time sets can be configured. One additional time set, represented by a -, repeats the previous time set.
⁹ For specifications in a Semiconductor Test System, refer to the Semiconductor Test System Specifications.
¹⁰ The Extended Voltage Range is an unwarranted mode of operation that allows the PMU to force voltages between 6 V and 7 V for applications that can tolerate more error than the normal force voltage accuracy.
