•RF accuracy (typical): +/- 5%.

•Frequency: 75-110 GHz (up to 1.5 THz with a taper)

A table in the VDI PM5B Operational Manual (Appendix 2) provides the values for

the Cal Factor setting if an additional taper is added. The optional waveguide

tapers have a flat frequency response, so only one Cal Factor value is set on the

PM5B front panel for the waveguide band. The loss of the WR10 sensor and taper

values are to be added together for the Cal Factor setting and rounded to the

nearest 0.1 dB value.

The WR10 75-110 1" section on the sensor head is NOT to be removed.

Add the taper to the WR10 section.

The PM5B calorimeter has a flat frequency response and is calibrated with a NIST traceable

DC source. Cal factor setting is not required unless a taper is added for extended frequency

use.

1. Tapers are optional. They can be ordered with the N1913PM5B.

Keysight N1913PM5B Product Note

Connecting the N1913PM5B

1. Ensuring ESD precautions, unpack and remove the products from their

packaging. Keep all connector covers to reinstall after use.

2. Connect the sensor head cable on the front panel, the 9 Vdc power supply, and (if

using software) the USB cable to the rear panel on the PM5B power meter. See

Figure 1 and Figure 2 below.

Figure 1 N1913PM5B with Sensor and Cable Connected to the Front Panel

Figure 2 N1913PM5B with Power Supply and USB Cable Connected to the Rear Panel

The USB connection is usually very snug and may require some additional

pressure to insert or remove completely.

Keysight N1913PM5B Product Note

Operation Example

1. Refer to the VDI PM5B Operation Manual for details. See page 3 for a link.

2. Load the software (optional - software not required for manual operation).

3. On the front panel, set the Range Switch to Remote and Cal Factor Switch

to 00.0 (Figure 3).

(Figure 4).

5. Start the PM5B control program (optional - not required with manual operation).

6. Enter serial number, for example "520V" (optional - not required with manual operation).

7. After the PM5B warms up and the temperature stabilizes, press zero on the front

panel.

8. Set the Internal Calibration Switch on the rear panel to 1 mW and read the meter

at 1.000 ± .050 (allow meter to settle before and after setting switch. This verifies

the N1913PM5B is functioning correctly).

9. Turn off the Internal Calibration Switch (OFF/EXT).

Operation Check Example

Remote or 2 mW Range

10.Connect the sensor to the DUT, an SGX or VNAX set to 110 GHz frequency, and

power level at 0 dBm (1.00 mW).

11.Set Calibration Factor Switch (dB) on PM5B front panel to 00.2 for WR10 band.

12. Ensure DUT power is off and the meter reading is stable. Press the PM5B front

panel "Zero" button.

13. Turn on RF and measure the power set on the source. Measure 1.000 mW ± your

accuracy in settling the power level, and ± 0.050 mW estimated accuracy.

Measurement Example

WR10 Sensor with pre-installed WR10 Section, 110 GHz, 1 mW (0 dBm)

14.Connect a WR6.5 or WR8.0 taper to the WR10 sensor. Do not remove the WR10

section!

Nickel-plated; tapped holes are easily stripped. Keep waveguide in place

Keysight N1913PM5B Product Note

15. Set Calibration Factor Switch (dB) on PM5B front panel to 0.3 dB for WR6.5 and

WR8.0 (see table in VDI PM5B Operational Manual - Appendix 2 for current listed

values). Note: Connect WR10 flanges of sensor and taper together for best

match. The smaller opening should face your DUT.

16. Connect sensor to DUT, set frequency to 110 GHz, and power level to 0 dBm

(1.00 mW), RF OFF.

17. Ensure DUT power is off. On the front panel of the PM5B, press "Zero."

18. Turn RF on and measure power. Measure 1.000 mW ± your accuracy in setting

the power level and ± 0.050 mW accuracy.

•PM5B calorimeter amplitude response is flat at ± 5% across a frequency band

of 75 - 110 GHz.

•Calibrated at DC to NIST standards.

•Only the loss of the added tapers requires a Cal Factor dB setting, otherwise it

remains at 0.2 dB for W-Band measurements.

•A "Zero" of the PM5B should be done after the calorimeter is at a stable

temperature.

•Measurement should be recorded after the reading stabilizes (see response

time below).
