Agilent Technologies E8257D Option H60/H65 User's and Service Guide Supplement

This manual supplement describes the differences in the E8257D Option H60 and H65 in comparison to the E8257D standard instrument. Refer to the PSG E8257D/67 Signal Generators User's (E8251-90353).

Description

The E8257D Option H60 and H65 provide a double-balanced microwave mixer that is installed internally on the rear panel with connectors for easy access to the mixer ports. These options can be used with another source, such as the E4438C or E8267D, to upconvert an RF frequency to 65 GHz or downconvert an RF frequency to DC (Option H60) or 1 GHz (Option H65).

It is recommended that Option H60 be ordered with Option 567 to utilize the Option H60 frequency range of 65 GHz. It is also recommended that Option H65 be ordered with Option 520, 532, or 540. The Option H65 mixer has an internal LO frequency doubler that enables the use of an E8257D Option 520 to upconvert a 20 GHz RF frequency to 60 GHz. Option 1EA is also recommended for Option H65 due to the mixer requiring more power for optimal performance.

Refer to the microwave mixer data sheets, Figure 1 on page 4 and Figure 2 on page 5 for further information regarding the Option H60 and H65 mixer nominal performance.

Operational and Verification Procedure

The E8257D Option H60 or H65 can be used to upconvert or downconvert the frequency of your source. Refer to Figure 3.

CAUTION: Inputs are ESD sensitive. It is recommended to keep connector covers on when not in use. Refer to "Electrostatic Discharge Protection" on page 22.

1. Connect the adapter to the E8257D Option H60/65 RF Output. Refer to Table 2 on page 9.
2. Connect the RF cable (5063-9820) from the adapter to the LO Port on the E8257D rear panel.

Figure 3 Rear Panel

The rear panel shows connections for ALC INPUT, 1 GHz REF IN, and MIXER PORTS (LO, IF, RF), as well as a 1 GHz OUT port.

Upconverting the Frequency

The upconverted frequency signal can be measured on the RF port on the E8257D Option H60/H65 rear panel.

1. Preset the instrument with Option H60/H65.
2. Set the power level to +13 dBm. Refer to Input 1 dB Compression for optimal LO Input Power in Figure 1 on page 4 and Figure 2 on page 5.
3. Connect your source to the E8257D Option H60/H65 IF port on the rear panel, using a 3.5 mm cable such as the (5062-6674).
4. Connect the second cable (5360-9820) to the RF Port.
5. To upconvert your source frequency, set the E8257D Option H60 frequency to the desired RF Output frequency minus your source frequency. For Option H65, set the frequency to the desired RF minus your source frequency and divide by 2. (The IF is subtracted from the upconverted RF for the LO frequency).

NOTE: Filtering may be required to remove unwanted signals. The RF Output frequency will have the difference of the E8257D Option H60/H65, as well as the two original frequencies, along with the sum upconverted product.

Equation 1 Upconverted Frequency (H60)

Upconverted RF = LO(E8257DH60) + IF(yoursource)

Equation 2 Upconverted Frequency (H65)

Upconverted RF = LO(E8257DH65) × 2 + IF(yoursource)

NOTE: The LO Port has a frequency doubler on the LO Input (H65 only). The E8257D Option H65 frequency output will be set to half the desired LO frequency.

Downconverting the Frequency

The downconverted frequency signal can be measured on the IF port on the E8257D Option H60/H65 rear panel.

1. Preset the instrument with Option H60/H65.
2. Set the power level to +13 dBm. Refer to Input 1 dB Compression for optimal LO Input Power in Figure 1 on page 4 and Figure 2 on page 5.
3. Connect your source to the E8257D Option H60/H65 RF port on the rear panel, using a 2.4 mm cable such as the (5063-9820).
4. Connect the cable (5062-6674) to the IF Port.
5. To downconvert your source frequency, set the E8257D Option H60 frequency to your source frequency minus the desired IF Output. For Option H65, set the frequency to the source frequency minus the desired IF Output frequency and divide by 2. (The IF is subtracted from the upconverted RF for the LO frequency).

NOTE: Filtering may be required to remove unwanted signals. The IF Output frequency will have the sum of the E8257D Option H60/H65, as well as the two original frequencies, along with the difference down converted product.

Equation 3 Downconverted Frequency (H60)

Downconverted IF = RF(yoursource) - LO(E8257DH60)

Equation 4 Downconverted Frequency (H65)

Downconverted IF = RF(yoursource) - LO(E8257DH65) × 2

NOTE: The LO Port has a frequency doubler on the LO Input (H65 only). The E8257D Option H65 frequency output will be set to half the desired LO frequency.

Electrostatic Discharge Protection

Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the network analyzer. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. To prevent damage to the instrument:

• Always have a grounded, conductive table mat (9300-0797) in front of your test equipment.
• Always wear a grounded wrist strap (9300-1367) with grounding cord (9300-0980), connected to a grounded conductive table mat, having a 1 MΩ resistor in series with it, when handling components and assemblies or when making connections.
• Always wear a heel strap (9300-1126) when working in an area with a conductive floor. If you are uncertain about the conductivity of your floor, wear a heel strap.
• Always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.
• Always ground the center conductor of a test cable before making a connection to the analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the cable.

Figure 3 ESD Protection Setup

This diagram illustrates the ESD protection setup, showing a grounded wrist strap connected to an anti-static mat, which is placed in front of the test equipment. A note indicates that a 3-wire line power cord with proper connection to ground must be used for ESD protection.
