Troubleshooting of R&S EPL1000

Before executing the automatic sequence, press the dropdown menu next to the [RUN] key and select "Scan Table (All)" instead of "Single Range".

If multiple lines (L, N, PE) of LISN need to be measured, first check the lines to be measured in "LISN Control", and then start "Multi Line Scan". EPL1000 will automatically switch lines and repeat scanning tables.

6.2 Missing key graphics or data during report generation

Fault phenomenon:

The built-in report generator is used to save PDF reports, but the report only includes scanned limit line graphs and lacks click through rate analysis results or spectrograms.

Setting method:

Before generating the report, the measurement result window that needs to be included must be placed in the foreground. For example, to save the click rate analysis results, first switch to the "Click Rate" results interface.

Press the 【 REPORT 】 key and select 'Create Report'.

In the "Content" tab, check the required content such as "Screenshot of current display", "Limit Line Table", "Peak List", etc.

If click through rate analysis requires detailed channel statistics data, it is also necessary to check "Click Details".

Select Template: Users can customize template files (. dotx) and place them in the/Templates/directory on a USB drive. EPL1000 will insert data and graphics according to the template layout.

The generated report can be saved in PDF or Microsoft Word format and supports adding the company logo and tester signature.

Remote control and software integration failure

7.1 SCPI command unresponsive or timed out

Fault phenomenon:

When sending SCPI commands via Ethernet or GPIB (such as "FREQ: STAR 150kHz"), EPL1000 does not execute or returns the error "-113, Undefined header".

Troubleshooting steps:

Network connection: Use the ping command to test if the IP address of EPL1000 is reachable. If it doesn't work, check the network cable and switch settings, or try a cross line direct connection.

Ports and protocols: SCPI commands are typically transmitted through ports 5025 (Telnet) or 23 (Telnet). Confirm that the port used by the upper computer software is correct. In the LAN settings of EPL1000, "SCPI over Telnet" needs to be enabled.

Command syntax: Pay attention to the case sensitivity of EPL1000? SCPI generally does not differentiate, but certain parameters require capitalization. It is recommended to write completely according to the programming manual. Common error: Missing units (e.g. kHz cannot be omitted in "150kHz").

GPIB address: If using GPIB option R&S ® EPL1-B10， Confirm that the GPIB address matches the settings of the upper computer (default 28) and that there are no address conflicts on the bus.

Reset communication stack: In [UTIL] ->"Remote Control", execute "Reset SCPI Interface".

7.2 R&S ELEKTRA software cannot recognize EPL1000

Fault phenomenon:

After installing the R&S ELEKTRA EM testing software, EPL1000 cannot be found when adding devices, or "Instrument not responding" is displayed.

Solution:

Ensure that the ELEKTRA software version supports EPL1000 (requires Ver 2.0 or higher).

In the "Hardware" configuration of ELEKTRA, select "Add Instrument", type "EMI Receiver", and model "EPL1000".

We recommend using VISA over TCP/IP as the connection method. First, enable the "VXI-11" protocol on EPL1000 (SETUP ->"LAN" ->"VXI-11" set to On).

Manually enter the IP address of EPL1000 for detection.

If it still fails, try using R&S ® Connect VISA Tester separately to verify correct driver installation.

Maintenance, Calibration, and Data Protection

8.1 Measurement drift or poor repeatability

Possible reasons:

The internal reference oscillator of EPL1000 is aging, or the ambient temperature exceeds the working range (nominal+5 ° C to+40 ° C). It is recommended to calibrate once a year. Before use, preheat the instrument for at least 20 minutes until the internal temperature stabilizes.

Self checking function:

Press 【 UTIL 】 ->'Self Test' to execute the 'Receiver Performance Test', which can quickly verify frequency accuracy, amplitude linearity, noise floor, etc. If self inspection fails, it is necessary to return to the factory for repair.

8.2 Sensitive Data Protection - Removable Storage Modules

For EPL1000 used on multiple customer sites or testing involving military projects, data security is crucial. EPL1000 provides R&S services ® EPL1-B19 can replace SSD storage packs. Operation steps:

Turn off the device and disconnect all power sources.

Use a screwdriver to open the bottom storage compartment cover and remove the SSD module with controller.

Insert another blank SSD, EPL1000 will automatically initialize and load firmware after restarting.

The data in the original SSD is completely isolated and cannot be read by new users.

When handing over the instrument to other departments or customers, it is recommended to remove the SSD first to ensure that there is no residual data.
